Most trailer jacks are sold on capacity alone, and that is how people end up with a jack that buckles, bogs down or breaks the tongue. A jack is not rated by how much the whole trailer weighs; it is rated by the weight sitting over the coupler, and for a loaded gooseneck, car hauler or dump trailer that number climbs fast. Getting the best trailer jacks for heavy trailers means matching the screw drive to your real loaded tongue weight, then checking lift range and mounting style against your frame.
We pulled the specs, owner feedback and warranty terms for ten jacks that show up constantly in trailer-owner discussion, spanning manual A-frame, weld-on square tube and powered 12V units. A few of them are what I would call the honest answers to heavy-duty questions, and a few are honest warnings. To be clear about the basis: everything here comes from manufacturer specifications, aggregated owner reviews and recurring themes in trailer forums, not from a controlled load test in our own yard. That matters for the numbers quoted, and I flag where owner reports conflict with the spec sheet.
The lineup runs the whole middle of the category rather than just the manual weld-on boxes everyone else lists. Capacities here span 5000 lb to 8000 lb, with one 7500 lb powered unit, and the mounting styles cover bolt-on swivel, direct weld-on and drop-in replacement of a factory electric jack. If you are still working out what you need, our trailer hitch roundup covers the coupler side, and boat trailer picks matters if the salt-water life is what you are protecting the jack from.
One thing worth saying up front: almost nothing in the 5000 lb class is genuinely overkill for a mid-size utility trailer, and going bigger than you need adds crank weight and bulk for nothing. Trailer owners on r/MechanicAdvice and AgTalk threads consistently advise sizing above your actual tongue weight, but they also consistently warn against buying 12,000 lb steel for a 1,500 lb tongue. Buy for the trailer you actually tow, then add margin.
Top 3 Trailer Jack Picks for Heavy Trailers (September 2026)
The three below are the picks I would put on my own trailer. Every other jack in the list is a legitimate choice for a specific setup, but these three cover the widest range of real heavy-trailer needs.
VEVOR 5000 lb A-Frame Jack
- 5000 lb capacity
- 15 in vertical travel
- 3-level drop leg
- Swivel bolt-on or weld-on
Kohree 5000 lb Electric Jack
- 5000 lb dynamic / 7500 lb static
- 5-position drop leg
- Two LED lights
- Auto-reset breaker
VEVOR 5000 lb Electric Jack
- 5000 lb capacity
- 10 in to 33.8 in range
- Two-year warranty
- LED work light
VEVOR takes the top slot on the strength of rating and volume of owner feedback together, with a 4.7 average across more than 1,200 reviews. The Kohree and VEVOR electric units both lead on warranty and published dual ratings, which most listings in this category skip, and that transparency makes them easier to size correctly.
Match Your Jack Capacity to Loaded Tongue Weight
A jack’s capacity number is a load limit, not a recommendation, and the number that decides your purchase is loaded tongue weight: the weight pressing down on the coupler ball with the trailer fully loaded. Start there, then keep a safety margin of roughly 25 percent above your measured figure. The 60/40 rule gives you a starting estimate for an unknown trailer: put about 60 percent of the cargo weight ahead of the axle and 40 percent behind, which lands tongue weight at roughly 10 to 15 percent of total loaded trailer weight. A 7,000 lb loaded trailer usually lands in the 700 to 1,050 lb tongue range, which a 5000 lb jack handles with room to spare.
Static and dynamic ratings are not interchangeable, and this is the single most misunderstood spec in the category. Static load capacity is the weight the jack can hold parked, essentially the load bearing straight down through the tube. Dynamic lift capacity is the weight it can raise while the screw is turning, which is always lower because the drive is doing work at the same time. Kohree and POLESTAR both publish both figures at 7500 lb static and 5000 lb dynamic. Listings that publish a single number rarely tell you which kind it is, so treat a lone capacity figure as a static figure and assume the usable lifting number is lower.
On gooseneck and fifth-wheel rigs, the equivalent number is pin weight, and it behaves differently. Pin weight is the portion of trailer weight transferred through the kingpin, and it is what actually loads the jack. Owners sizing these rigs report staying at or above the manufacturer pin-weight figure rather than the GVWR, and never sizing a tongue jack for the full trailer weight. If you are in that category, treat the ranges below as a floor, not a target.
As a rough guide, a 1,000 to 1,500 lb tongue calls for a 2000 lb jack, a 1,500 to 2,500 lb tongue suits a 5000 lb unit, and anything approaching 3,000 lb or more on the coupler pushes you toward the 8000 lb class and beyond. Trailers in this roundup all sit in the 5000 to 8000 lb band, which covers heavy equipment, livestock, car hauler and large boat work without pushing into pallet-jack territory.
All 10 Trailer Jacks at a Glance in 2026
Everything below is rated on the same set of numbers so you can scan quickly: rated capacity, mounting type, lift range and what it is genuinely best at. Where a listing mixes static and dynamic figures, the more conservative number is the one I used.

1. VEVOR 5000 lb A-Frame Jack – 15 Inch Travel and a Swivel Mount
VEVOR 5000 lbs A-Frame Trailer Jack, 15″ Vertical Travel, Adjustable Drop Leg, for Horse, Utility, Yacht Trailers
5000 lb capacity
15 in vertical travel
9.65 in to 24.64 in range
11 lb unit weight
Pros
- 4.7 average across 1211 reviews
- Galvanized tubes with powder coat finish
- Swivels out of the way for storage
- Bolts on or welds on
- 3-level drop leg for uneven ground
Cons
- 15 in travel is short for high-frame trailers
- Manual crank only with no powered option
- Detachable handle must be kept with the jack
This is the jack I keep coming back to for mid-weight heavy trailers because the combination of rating and owner volume is hard to argue with. A 4.7 average over more than 1,200 reviews is a stronger signal than a 5.0 across 42 listings, and the fit-and-finish complaints owners raise are minor rather than structural. Galvanized inner and outer tubes with a powder coat over them is exactly the corrosion package you want if your trailer lives outside or sees road salt.
The swivel is the feature I would not give up. The body folds parallel to the tongue for storage, which matters if you are parking a loaded equipment trailer in a tight bay, and it also lets you approach the coupler from an angle that a fixed jack forces you to work around. At 11 lb the whole unit is light enough to reposition by hand, which matters if your tongue geometry is awkward.
The 15 in vertical travel figure is the honest limitation. Listed lift runs from 9.65 in to 24.64 in, which is fine for a standard A-frame tongue but leaves little room if your frame sits high or you tow onto a steep driveway. The 3-level drop leg adds coarse extension in jumps before the screw takes over, and owners report it does a decent job of keeping a trailer level on soft or sloped ground rather than fighting the terrain with crank force alone.
One detail worth planning for: the crank handle detaches, which is good for storage and bad for lending the jack to a neighbor. I would note that some listings describe this as bolt-on or weld-on capable, so confirm the bracket style against your existing tongue holes before you order. There is also a 2000 lb version in the same family if your tongue weight is modest.
Who this jack suits
Owners of equipment trailers, small car haulers and utility trailers running roughly 1,500 to 2,500 lb of tongue weight will never approach the limit. The swivel and drop leg combination makes it a good fit for anyone who unhitches solo in tight spaces, because you can reposition the jack instead of maneuvering around it.
If you tow a boat, the galvanized tubes and powder coat give you a fighting chance in a salty launch ramp environment, and the fold-away swivel keeps the jack out of the way during launching. For a genuinely heavy tongue, step up to the 8000 lb weld-on later in this list.
Who this jack does not suit
A high-frame travel trailer or a gooseneck with real pin weight will want more lift range than 24.64 in extended, and cranking a loaded tongue that high is exactly the shoulder strain that makes people look at electric units. If your hitch ball height sits well above standard, this is not the pick.
Nobody with a back, shoulder or wrist problem should crank this by hand under load. There is no powered option in this jack and no drill socket adapter, so the effort is on you every time. The 5000 lb rating also says nothing about a trailer whose loaded tongue weight approaches that figure, since you would be lifting with little margin left.
2. YOMILINK 5000 lb A-Frame Jack – Five-Level Drop Leg for Uneven Ground
YOMILINK 5000 lbs A-Frame Trailer Jack, 15″ Lift, Adjustable Drop Leg
5000 lb capacity
5-level drop leg
23.2 in to 45.6 in range
14 lb unit weight
Pros
- 4.8 average
- the highest rating in this group
- 2.36 in high carbon steel tube
- Grease nipple and base drainage holes
- Sidewind crank for clearance
Cons
- Bottom plate is not removable
- Included bolts are too short for many tongues
- No guidance on which grease to use at the nipple
This is the tallest-lifting manual jack in the group and the only one whose listed range starts and ends well above everything else on the list. Adjusting from 23.2 in to 45.6 in gives you room to work on a high tongue or a steeply pitched site where a 24 in ceiling jack simply runs out of screw. The 4.8 average is the highest rating of the ten, though the 459 reviews behind it are a thinner sample than the leader’s.
The 2.36 in tube is the real engineering story here. A wider tube resists side loading and buckling under crank force, which is why owners describe the cranking as smooth and controlled rather than gritty. Five drop-leg levels also mean you can extend in coarse steps and use the fine screw only for the last few inches, and that is where the effort savings show up on a heavy tongue.
Two details separate this from a generic budget jack. A grease nipple at the thrust bearing means the screw drive can be serviced rather than replaced, and drainage holes in the base plate let water and road grime escape instead of sitting against the steel. Grade 5 / GB 8.8 studs throughout are also above what most jacks in this price tier use. Galvanized inner and outer tubes with a powder coat handle the salt and rain.
The installation catch is the bottom plate, which is welded rather than removable. Under a low tongue the two-piece tube is genuinely awkward to assemble because you cannot separate the sections to get them past the frame rail. Plan to install with the tongue already down, or budget extra time and a second pair of hands. Owners also report the supplied bolts running short on thicker tongue steel, so buy Grade 5 hardware in the length you need rather than trusting the kit.
Who this jack suits
High-frame trailers, raised goosenecks and steep driveways are where this one earns its keep. If you have ever hit the end of your screw drive with a heavy tongue still on the ball, the 45.6 in maximum height is the feature that solves it. Equipment and landscaping trailers parked on uneven ground also benefit from the five-level drop leg.
For anyone planning to maintain their gear, the grease nipple is a genuine advantage over jacks in this class with no serviceable fittings. Sidewind crank orientation also keeps the handle away from the trailer body, which helps in tight parking situations and around tailgates.
Who this jack does not suit
If your trailer has a low, flat tongue with a lot of side clearance, the tall retracted height gets in the way and the fixed bottom plate makes fitting it harder than it should be. Budget owners on very light trailers will also find the 14 lb unit and the wider tube more than they need.
Anyone with shoulder limits will still be cranking, and manual work is manual work no matter how smooth the gearing. And if your tongue weight is genuinely near 5000 lb, the lift rating is a ceiling rather than a comfortable working load, so size up to a heavier class in that situation.
3. VEVOR 8000 lb Square Weld-On Jack – the Heaviest Capacity Here
VEVOR 8000lbs Heavy-Duty Square Direct Weld on RV Jack, 15-1/4 Inches Lift, Adjustable Drop Leg, for Lifting RV, Horse, Utility, Yacht Trailers, TJD-7000S
8000 lb capacity
15-1/4 in lift stroke
24.88 in to 52.6 in range
23.4 lb unit weight
Pros
- Heaviest rated capacity in this roundup
- Square tube resists side flex under load
- Direct weld-on or removable lug mounting
- Galvanized inner tube with powder coat
- Pinned drop foot folds for storage
Cons
- Weld-on is permanent if your frame layout changes
- One owner reports loose internal clearances
- One shipment arrived missing a part
This is the only jack here rated to 8000 lb, and it earns that place in the line-up. If your loaded tongue weight is climbing toward 3,000 lb, this is where you start looking, because everything ahead of it in the list is a 5000 to 7500 lb unit. The 4.7 average sits alongside the leader despite a smaller 419-review base, so treat it as well-regarded rather than proven at volume.
Square tube is the reason it feels different under crank. Round-tube jacks twist under side load, especially at extension, and that flex is what makes a jack feel vague. A square heavy-duty carbon steel tube across a 15-1/4 in stroke is meaningfully more rigid, and builders who weld frames tend to notice it immediately. A 23.4 lb unit is heavy, which reads as mass rather than a problem on a permanent mount.
Mounting flexibility is unusual for a weld-on jack. It welds directly to the frame, and the removable lug option gives you a serviceable swap-out path if the jack ever needs replacing without cutting the frame. The multi-level drop leg handles leveling, and the pinned drop foot cranks fully up and down for storage. Galvanized inner tube with a powder coat on the body covers the usual corrosion exposure.
Maximum extended height of 52.6 in makes this the tallest travel figure in the roundup, and that is a genuine advantage for tall horse and utility trailers. What I would watch is the small stuff: an owner report of looser-than-ideal internal clearances for the price, and a shipment that arrived missing a part. Neither is serious, but both argue for checking the hardware bag before you weld anything.
Who this jack suits
Trailer builders, and anyone whose tongue weight has outgrown a 5000 lb jack, are the natural owners. Livestock and horse trailers with tall frames benefit from the 52.6 in reach, and car haulers carrying several vehicles put real, steady weight on the coupler that smaller jacks simply should not be asked to carry.
The removable lug option makes this a better long-term choice than a purely permanent weld-on if you expect to swap equipment. Square tube rigidity also pays off on uneven ground, where a jack that flexes loses the fine adjustment you need to get the coupler onto the ball.
Who this jack does not suit
Owners of small utility and landscaping trailers should not buy this. A 23.4 lb unit on a light tongue makes the whole assembly heavier and harder to lift over an obstacle, and the extra capacity is money and weight spent for nothing. If your tongue weight sits under 1,500 lb, a smaller jack is the honest answer.
It is also not a swap-in for an existing bolt-on pattern, since welding is the primary mount. And without a powered drive, lifting an 8000 lb-rated jack under real load is a serious cranking effort that will test anyone with joint problems.
4. Uriah Products 5000 lb Electric Jack – 7-Way Connector Ready
Uriah Products Electric Trailer Jack with 7-Way Connector, 12V, 5000 Lbs Lift Capacity – Heavy-Duty Stabilizer for RV, Boat, Utility, and Off-Road Vehicles
5000 lb capacity
Ball screw with brake motor
9 in to 31.5 in travel
22.3 lb unit weight
Pros
- Largest review base in this roundup at 3227
- Ball screw drive gives smooth quiet raising
- Manual crank included for outages
- LED light and weatherproof cover included
- ASABE compliant
Cons
- Motor is noticeably loud
- Two-contact 7-way plug is not powered by some newer trucks
- Reported motor wiring failure with a 1-year warranty
With 3,227 reviews, this is the most widely used electric jack in the group, and that volume tells you something a 5.0 across a few dozen listings does not. The 4.2 average is the lowest of the ten, which is an honest signal that something is not right for a set of owners, and it is worth reading what they say before you commit.
The drive is the strength. A ball screw with a brake motor raises and lowers smoothly and quietly, and the brake is what holds position when you release the switch. Lift runs from 9 in retracted to 31.5 in extended, with a 4.5 in minimum height, giving useful range for a mid-height tongue. A manual crank handle is included, which is the single most important feature on any electric jack.
The wiring is where the trouble is. This jack uses a two-contact 7-way plug, and multiple owners report newer trucks showing a no trailer detected message because those trucks do not send power to that configuration. The fix, described repeatedly in reviews, is hard-wiring to the battery. If your truck is newer, factor that extra step into the install before you buy.
Motor noise is the other recurring theme, with owners noting it is unsuitable for late-night campground use. There are also reports of motor wiring burning out after limited use under a 1-year warranty, and lift speed that owners compare unfavorably to hand cranking. Any jack with a manual crank handle gives you a fallback for all three of those problems.
Who this jack suits
RV, boat and utility trailer owners with 1,500 to 2,500 lb of tongue weight get the most from it, particularly anyone who unhitches solo or at night and does not want to crank. Because the hole pattern matches a standard manual jack, swapping it in over an existing electric jack is a straightforward bolt-on job.
Owners upgrading from a smaller 3500 lb unit will feel the difference in smoothness more than in raw speed. It is also a reasonable choice for a boat trailer, though you would want to rinse it with fresh water after every saltwater launch regardless of the finish.
Who this jack does not suit
Anyone whose truck does not power a two-contact 7-way plug will find the install more involved than the listing suggests, and the battery connection needs to be done properly. If you cannot route a wire to the battery, this is not the clean drop-in it appears to be.
Quiet campsites are a poor match given the motor noise, and the 1-year warranty is the shortest of the powered units here. A 1-year warranty on a jack that is exposed to weather and road salt is thin, so budget for a possible replacement in a harsh environment.
5. Kohree 5000 lb Electric Jack – Most Versatile Powered Jack
Kohree Electric Trailer Jack 5000lbs with Wiring, Heavy Duty A-Frame
5000 lb dynamic / 7500 lb static
5-position drop leg
9.8 in to 31.7 in range
21.2 lb unit weight
Pros
- Publishes both dynamic and static ratings
- 5-position drop leg adds 8 in of height
- Two LED lights for night hookup
- Auto-reset circuit breaker protects the motor
- Alloy steel with anti-rust coating
Cons
- Power lead is too short to reach the battery without splicing
- One owner reported a bent footpad after three uses
- Requires drilling a new hole if tongue bolts are seized
Kohree is the pick for the most common heavy-trailer case there is: a 1,500 to 2,500 lb tongue on a camper or utility trailer where you want power without spending heavily. The 4.4 average across 1,198 reviews puts it clearly ahead of the field on rating, and the published dual rating of 5000 lb dynamic and 7500 lb static is better disclosure than most listings in this category manage.
The 5-position drop leg adds 8 in of height on its own, and combined with a 9.8 in minimum and 31.7 in maximum you get a wide working range without turning the screw the whole way. A built-in circuit breaker trips on high amperage and auto-resets after roughly two minutes, which protects the motor when the jack meets an obstruction or an overload.
Alloy steel with an anti-rust coating, a weatherproof cover and two LED lights aimed at the working area is a sensible package for the money. Owners consistently report a bolt-on install inside half an hour, a clearly labelled retract and extend switch, and a smooth motor that beats hand cranking. The manual crank in the box is a genuine plus at this tier.
The recurring complaint is the power lead being too short to reach the battery without splicing, so plan on an extension or a proper connector. There is also an isolated report of a bent footpad after only three uses on a 4,400 lb trailer, with the manufacturer declining a replacement, which is worth keeping in mind if you carry close to capacity. Seized tongue bolts may mean drilling a new hole, so check your hardware before you start.
Who this jack suits
Campers, small travel trailers and utility trailers in the 1,500 to 2,500 lb tongue range are the ideal match, and the two LEDs genuinely help when you are hooking up after dark. Anyone who wants to stop cranking without stepping up to a premium electric jack will find the value here hard to argue with.
The five-position drop leg also makes it useful on soft or sloped ground, since you can extend in stages rather than cranking continuously against an incline. A 21.2 lb unit is also manageable to handle in a hitch position without a second person.
Who this jack does not suit
A trailer with a tongue bolt pattern you cannot match will need drilling, and the short power lead is a real inconvenience if your battery sits far forward. Anyone who needs to reach the jack without walking back to the truck should look at a remote-controlled unit instead.
And the 1-year manufacturer warranty is the shortest offered among the powered jacks here. Warranty length matters more than most buyers expect, because these are exposed to water, salt and mud on every trip.
6. VEVOR 5000 lb Electric Tongue Jack – the One With a Two-Year Warranty
VEVOR Electric Trailer Jack, 5000 lbs, Heavy Duty RV Electric Power Tongue Jack with 2 Way Connector, Manual Crank Handle & Weatherproof Jack Cover, 10″-28.3″ Lift, for RVs, Trailers & Campers, Black
5000 lb capacity
10 in to 33.8 in range
LED work light
22.9 lb unit weight
Pros
- Two-year manufacturer warranty
- longest in this group
- Highest published lift range among the electric units
- Galvanized carbon steel construction
- Multiple hole patterns for side or front mounting
Cons
- Slow lift speed
- with some owners preferring hand cranking
- Inline fuse may ship uninstalled in its holder
The reason this one ranks where it does is warranty length. A two-year manufacturer warranty on an electric tongue jack is unusually good in this category, where one year is the norm, and warranty length is one of the clearest trust signals owner-forum buyers point to. The 4.3 average across 1,173 reviews backs that up as a solid, mainstream choice.
It also has the tallest published lift range of the powered units, running from 10 in to 33.8 in, which helps on raised tongues and steeper approaches. Galvanized carbon steel with a rust-resistant coating handles weather exposure, and multiple mounting hole patterns let you choose side or front mounting to clear a tailgate. An LED work light and a weatherproof cover are included.
Installation is where it wins reviews. Owners report under 30 minutes with basic tools, and the unit handles 800 lb tongue weights comfortably according to feedback. The included hand crank means you are never fully dependent on the motor, which is exactly what trailer owners say they want from a powered jack.
There are real negatives to weigh. Lift speed is slow, and some owners say it is slower than hand cranking, which undercuts the main reason to go electric. One owner reported the jack screw breaking in the first weekend of use, which is a serious complaint even as an isolated report. A more common irritation is an inline fuse that ships uninstalled in its holder, so the jack looks dead on first hookup until you seat it.
Who this jack suits
RVs, campers and utility trailers with moderate tongue weight in the 1,500 to 2,500 lb band are the natural fit, particularly for owners who value warranty coverage over raw speed. The long lift range helps if you tow onto a sloped site or your tongue sits high off the ground.
The hand crank makes it a safer first electric jack for anyone nervous about being stranded by a dead motor. Multiple hole patterns also mean it can go on more existing trailers than jacks with a single bolt pattern.
Who this jack does not suit
If you unhitch often and want the job done in seconds, slow lift speed will frustrate you, and hand cranking may genuinely be faster. The same applies to anyone who needs to reposition the trailer repeatedly on rough ground.
Trailer builders who weld their own frames would find little reason to consider an electric unit, since the drive and wiring add complexity with no benefit on a permanent mount. Very heavy tongues are also outside what a 5000 lb electric unit should be lifting.
7. POLESTAR 5000 lb Electric Jack – Drop-In Replacement
POLESTAR Electric Trailer Jack, 5000lbs Electric Power A-Frame Tongue Jack
5000 lb dynamic / 7500 lb static
Ball screw with brake motor
9 in to 27 in plus drop leg
21.7 lb
Pros
- Drop-in replacement for a standard 3500 lb electric jack
- Quieter and smoother than the factory unit it replaced
- Ball screw drive gives precise consistent lifting
- Can ground through a mounting bolt for a battery connection
Cons
- Non-standard inline fuse is hard to replace locally
- Does not allow tailgate clearance in the default orientation
This is the pick for one specific and very common job: replacing a tired 3500 lb factory electric jack without changing anything else. Owners report about 20 minutes for the swap because the bolt pattern lines up, and they consistently describe the result as quieter and smoother than the unit it replaces. The 4.4 average across 861 reviews is a good score for that specific upgrade path.
Like the Kohree, it publishes both figures: 5000 lb dynamic and 7500 lb static. The ball screw drive with a brake motor is a better mechanism than a cheaper gear-and-clutch design, and it is the reason the lift feels controlled. Range is 9 in retracted to 27 in, plus a 4.5 in drop leg, taking the working maximum to 31.5 in.
A built-in circuit breaker trips and auto-resets on high amperage, protecting the motor from an obstruction. LED lights are aimed at the ball and coupler rather than generally at the ground, which is a thoughtful detail. Alloy steel construction, a waterproof rain cover, a manual crank and a 1-year warranty round out the package.
Two things to plan for. The factory inline fuse is a non-common type, and owners report intermittent dead units traced straight back to it, which means you cannot just buy a standard blade fuse at a shop. Second, in the default mounting orientation it does not give tailgate clearance on a lifted truck, so check your hitch height and tailgate clearance before ordering.
Who this jack suits
Anyone swapping out a stock 3500 lb electric jack on an RV or camper gets an immediate capacity and smoothness upgrade for minimal effort. The mounting-bolt grounding trick for the battery connection is genuinely handy if you want to power without routing a dedicated wire.
It also suits owners who unhitch solo and want quiet operation, since smoothness and low noise are the standout owner remarks. A 1-year warranty is standard rather than strong, so treat the fuse issue as the real risk to plan around.
Who this jack does not suit
If you tow a heavy tongue on a truck with a tight tailgate gap, the default orientation will not work and you need a mounting change to fit. It is also not a new-build choice, since it assumes an existing 3500 lb jack bolt pattern rather than a general tongue.
Buyers who value support reach should know that customer service routing for this brand gets confused with the Polestar automaker, which owners report makes warranty help harder to obtain. And with a 1-year warranty against the two-year coverage on the other VEVOR electric unit, it is a value judgement rather than a risk-free buy.
8. KYX 7500 lb Electric Jack – Remote Control Operation
KYX Electric Trailer Jack 7500LBs,Electric Jack with Waterproof Cover
7500 lb capacity
Remote control operation
9.84 in to 32 in range
Internal circuit breaker
Pros
- Highest powered capacity in this roundout at 7500 lb
- Remote control lets you level from the truck or inside the trailer
- Three-bolt swap from a manual jack
- Anti-rust carbon steel with waterproof cover
- Hand crank and inline fuse included for backup
Cons
- Reported screw-drive bending and snapping in service
- Wires too short and shipped without connectors or bolts
- Underpowered for a 14000 lb dump trailer per one owner
The remote control is the reason to look at this one. Being able to raise and lower the trailer from the cab, or from inside while you line up the coupler, solves a real problem on sloped driveways and awkward sites. At 7500 lb it is also the highest-capacity powered unit here, which puts it in territory where you would expect an electric jack to struggle, and that tension is worth thinking about.
Physically it is a carbon steel body with an anti-rust coating, a multi-level adjustable height running from 9.84 in to 32 in, and an internal circuit breaker for overload and overheat protection. A hand crank handles power outages, and a waterproof cover is included. Installation is described as a three-bolt swap from a manual jack.
The reviews are genuinely split, and I would not paper over that. The positive camp praises the three-bolt swap, the remote, and the coating. The negative camp keeps reporting the same thing: a screw drive that bends and then snaps in service, leaving a trailer stranded. One owner also found it underpowered and slow for a 14,000 lb dump trailer, which is a fair warning about how far an electric drive stretches.
Wiring is the other issue. Owners report wires too short to reach the battery terminals, arriving without connectors or bolts, and a raise and lower switch that sticks and does not fit properly. Budget for extra wiring hardware and a proper connector set, and check the switch fit during the first test run rather than at the ramp with a loaded trailer.
Who this jack suits
Owners with a steep or awkward driveway who want to level without walking back and forth will get real value from the remote. At 7500 lb it also covers the upper end of what a tongue jack sees, so heavier equipment and car hauler trailers can look here rather than at the 5000 lb class.
Anyone replacing an existing manual jack with an electric unit and wanting a simple three-bolt conversion is a good fit. The hand crank means the remote is an addition to your options rather than your only way to move the trailer.
Who this jack does not suit
If you need a dependable drive for genuinely heavy duty work, the screw-drive failure reports are a legitimate reason to rule it out. A jack that snaps in service on a loaded trailer is worse than one that is slow, because it leaves you without a way down.
Owners who need long-term warranty backing should also be cautious, since the reported failures concentrate on the part most likely to fail. And if your battery is far from the tongue, the short wiring means the install will not be a simple swap after all.
9. Husky Super Brute 5000 lb Electric Jack – 18 Inches of Travel
Husky Towing 82022 Super Brute Electric Trailer Tongue Jack, 5000 lb Capacity, 18 Inch Travel, with Remote and 3 LED Lights, Bright Silver
5000 lb capacity
18 in travel with 6 in drop leg
3-sided LED lighting
30.1 lb unit weight
Pros
- Longest travel of any jack in this roundup
- Wireless remote with power alert warning
- 3-sided high-output LED lighting
- Alternate mounting holes allow tailgate clearance
- Responsive warranty replacement service
Cons
- Switch failures reported roughly every three years
- No battery eyelet terminal included
- No mounting bolts
- only lock washers
Two figures make this the most capable unit here in specific ways. Travel is 18 in with a 6 in drop-down leg, the longest in the roundup, and owners report it lifting 10,000 lb trailers without straining. If your tongue sits high or your hitch ball needs more range than a standard jack offers, this is the one that solves it.
Lighting is the other differentiator. Three-sided high-output LEDs light the hitch area from multiple directions, which is the feature that turns a 10 pm hookup from a guessing game into a quick job. The wireless remote includes a power alert warning system, and alternate mounting holes allow side mounting for tailgate clearance on a lifted truck.
The drive is a low-friction ball screw designed for smooth, low-noise operation, and alloy steel construction keeps it rigid. At 30.1 lb it is the heaviest unit in the list, which is expected given the 18 in stroke, and it needs a solid mount to work against. Owners also report responsive warranty replacement service, which counts for more than the warranty length alone.
The reported weak point is the switch, with failures coming up roughly every three years even with a waterproof cover in service. One owner also lost a remote fob after a few uses, and the package does not include a battery eyelet terminal for a direct battery hookup, so you will need an extra part. Mounting bolts are not included either, only lock washers, which is a small annoyance during install.
Who this jack suits
Tall trailers, high hitch balls and lifted trucks are where the 18 in travel and side mounting pay off directly. Night hookups are the strongest case of all, and owners consistently single out the three-sided lighting as the reason they stopped struggling in the dark.
Owners who unhitch frequently and want to do it from the cab will like the wireless remote, and the power alert warning system tells you before the battery drops too low. If you tow near capacity, the reported lifting ability gives real margin over the rated 5000 lb.
Who this jack does not suit
At 30.1 lb and the top price tier of the electric units, this is hard to justify for a light trailer or light-duty use. A 1500 lb tongue does not need 18 in of travel or three-sided lighting, and you would be carrying the weight for nothing.
Owners who keep trailers long-term should also weigh the reported three-year switch failure against the fact that a switch failure means a dead jack until it is repaired. If you do buy one, the missing eyelet terminal and mounting bolts are add-ons to budget for on day one.
10. Bastion 5000 lb Top-Wind A-Frame Jack – Footpad Included
Bastion Distribution Top-Wind A-Frame Trailer Jack with Rectangular Footpad | 5000 lb Manual Crank Tongue Jack | Great for RVs, Campers, Boats, Utility Trailers & More | BJ-5000TW-1 / RFP
5000 lb stationary load capacity
14.8 in of vertical travel
11 lb unit weight
Powder-coated alloy steel
Pros
- Rectangular footpad and retaining clip included
- 4.7 average across 425 reviews
- Build quality above what the tier usually delivers
- Universal fit across RV
- boat and utility trailers
- Light 11 lb unit
Cons
- Cranking is hard with significant tongue weight
- Mounting bolts not included
- Only 6-month warranty
This is the pick when the trailer frame sits in a way that puts a sidewind handle into the trailer body, or when you simply prefer winding the handle over your head rather than out to the side. A top-wind jack keeps the handle vertical and centered, which is a better position for anyone with shoulder limits, and it also keeps the handle clear of a tailgate.
It rates 5000 lb of stationary load capacity with 14.8 in of vertical travel, and the 4.7 average across 425 reviews sits alongside the leaders on rating. The rectangular footpad ships pre-mounted with a retaining clip, which is a small thing that most competing jacks in this tier leave out, and it gives a wider, more stable ground footprint on soft surfaces.
Construction is powder-coated alloy steel for corrosion resistance, and the universal fit covers RVs, campers, boat trailers, jet ski trailers, fifth wheels and utility trailers. At 11 lb the whole unit is light to reposition, and the standard A-frame bolt pattern means a straightforward upgrade from a lighter jack. Owners call the build quality better than expected for the money.
The gearing is the complaint. Owners report cranking becomes hard when significant weight is on the tongue, which is the gearing talking rather than a defect. Mounting bolts are not included, and the 6-month warranty is the shortest in the roundup, so hold onto your receipt if anything arrives damaged.
Who this jack suits
Boat and jet ski trailers benefit from the included rectangular footpad, which spreads load on a wet ramp surface and keeps the jack from sinking into sand. RV and camper owners who want a clean, universal-fit upgrade from a lighter jack will find the bolt pattern straightforward.
If shoulder or wrist problems make a sidewind handle awkward, a top-wind handle rotates the effort into a position most people find easier. At 11 lb it is also the easiest unit here to lift into and out of a hitch position alone.
Who this jack does not suit
Heavy tongue weights are the wrong end of the range for this jack. Once real weight is on the coupler, owners report the cranking effort climbing sharply, and that is exactly the situation where a drop leg or a powered drive earns its place.
A 14.8 in travel figure also means little help on a high tongue or a steep driveway. And a 6-month warranty means a transit scratch or a bent footpad is on you, so inspect the package the moment it arrives.
Buying Guide: How to Choose a Heavy Duty Trailer Jack
Capacity is the first filter and the easiest one to get wrong. Size to loaded tongue weight, not to trailer weight, and add a 25 percent margin. Everything in this roundup handles up to a 2,500 lb tongue comfortably, and only the 8000 lb weld-on covers a tongue approaching 3,000 lb. Going further up means accepting crank weight you do not need.
Mounting style is the second filter, and it comes down to whether you own a welder. Weld-on square tube gives the most rigid, permanent solution and is standard on trailer builders. Bolt-on swivel brackets let you remove and reposition the jack, which is the practical default for most owners. Drop-in electric mounts assume an existing bolt pattern, usually from a factory 3500 lb unit.
Lift range matters more than most buyers expect. Retracted height has to clear your frame and coupler, and maximum extended height has to reach your target hitch ball height with margin. A 24 in ceiling will not service a raised tongue, which is exactly why the 45.6 in and 52.6 in figures on two of these jacks exist. Drop-leg levels trade fine adjustment for reduced crank effort, and a 5-position drop leg beats a 3-position one on rough ground.
Operation type is a lifestyle decision as much as a technical one. Manual sidewind or top-wind costs nothing and never fails electrically, but it puts the effort on your shoulder every single time. Drill-operated jacks sit in between. Electric 12V units add convenience, lighting and remote control, at the cost of a wiring install, a battery dependency and a motor that can fail. Hydraulic jacks belong to dump and equipment work rather than tongue mounting, and the 12,000 lb hydraulic class in the wider market is a different product from everything here.
Corrosion protection is decided by where the trailer lives. Galvanized tubes plus a powder coat is the strongest combination in this list. Zinc plating suits marine use where salt spray is constant, though a fresh water rinse after every launch does more than any finish. If you see road salt in winter, rinse the jack down and dry the screw drive before it sits.
Maintenance is where cheap jacks quietly fail. A grease zerk at the thrust bearing, which only the YOMILINK in this group has, is the difference between a jack that lasts a decade and one whose screw drive seizes in two seasons. Pump it every few hundred miles of use, or at minimum once a season, with a general-purpose lithium or marine grease. Keep the screw threads clean and lightly coated, and always store with the jack retracted to keep road grit out of the threads.
For gooseneck and fifth-wheel trailers, pin weight replaces tongue weight in the calculation, and it is often higher than people expect. Our teardrop trailer guide covers lighter rigs in more detail, and anything with a heavy kingpin setup needs the 8000 lb class or beyond rather than a 5000 lb unit. Measure before you buy, and do not rely on GVWR as a proxy for what the jack sees.
Frequently Asked Questions
What is the best brand of trailer jack?
For heavy trailers, the best-supported brands are the ones with real owner volume and published warranty terms rather than the highest single rating. In this roundup VEVOR leads on review volume and rating, while Husky and Bastion score well with hardware brands behind them. Look for a jack that publishes both static and dynamic capacity, includes a manual crank, and carries at least a one-year warranty.
Which brand of hydraulic jack is considered the best?
Hydraulic trailer jacks are a separate class used mainly for dump trailers and heavy equipment where you need to raise a loaded bed. They are not substitutes for a tongue jack, and the 12,000 lb hydraulic units on the market are chosen on lift height and ram force rather than a crank handle. If you own a dump trailer, match hydraulic capacity to the loaded bed weight, not to tongue weight.
What is the 60/40 rule for trailers?
The 60/40 rule is a loading guideline: put roughly 60 percent of cargo weight ahead of the axle and 40 percent behind it. On a typical trailer that produces tongue weight of about 10 to 15 percent of total loaded trailer weight, which is how you estimate the load on a jack before you measure it directly.
What is the best heavy-duty jack?
For most heavy trailers the best heavy-duty jack is a manual A-frame unit rated to 5000 lb, because it matches a 1,500 to 2,500 lb tongue without adding crank weight you will never need. If your tongue is heavier, step up to an 8000 lb weld-on square tube jack. For powered operation, a 5000 lb electric jack with a manual crank backup covers the same range with less effort.
Is a weld-on jack better than a bolt-on jack?
A weld-on jack is stiffer and more permanent because the weld transfers load directly into the frame, which is why builders prefer square tube weld-on units. A bolt-on jack wins when you want to remove, reposition or replace the jack later, and it is the only realistic option if you do not weld. Removable lug mounts give some weld-on jacks a serviceable middle path.
How do I keep a trailer jack from rusting?
Rinse the jack with fresh water after every saltwater launch, dry the screw drive before storing it, and keep the jack fully retracted so grit does not sit in the threads. A galvanized tube with a powder coat finish handles road salt well, and a grease zerk on the thrust bearing keeps corrosion and wear off the drive at the same time. Annual lubrication is enough for light use.
Final Verdict on the Best Trailer Jacks for Heavy Trailers
For most heavy trailer owners the answer is the VEVOR 5000 lb A-frame jack, with a 4.7 rating across more than 1,200 reviews, a swivel that folds away, and a 3-level drop leg that handles uneven ground without a fight. It suits trailers in the 1,500 to 2,500 lb tongue range, which covers equipment, utility, livestock and larger boat work. If your tongue is heavier, the VEVOR 8000 lb square weld-on is the only unit here rated for it. If cranking is the problem rather than capacity, the Kohree gives you the most powered value and the POLESTAR is the cleanest 3500 lb replacement.
Whatever you pick, measure your loaded tongue weight first, size 25 percent above it, and keep a manual crank in the truck. That last habit is the one piece of advice trailer owners agree on most consistently, and it has saved more people from a bad day than any brand on this list. For the coupler side of the connection, our trailer hitch roundup is the next thing to read.
