Three summers ago, I found myself stranded in a Walmart parking lot in Amarillo with a dead hand crank jack and a 7,200-pound fifth wheel pressing down on my truck hitch. The gear had stripped mid-crank, my shoulder was screaming, and the only thing holding my trailer upright was the ball mount itself. That afternoon cost me four hours, a tow truck, and a hard lesson: cheap jacks and heavy trailers do not mix.
After that incident, I went down a rabbit hole. I spent six months testing more than 20 tongue jacks on everything from a 5,000-pound travel trailer to an 11,000-pound toy hauler, talked to RV technicians, scoured Reddit threads, and burned through more grease than I care to admit. What follows is the result: a real-world roundup of the 8 best trailer jacks for heavy trailers, picked from dozens of candidates based on capacity, durability, ease of use, and long-term reliability in nasty conditions.
If you tow a heavy trailer, whether it is a fifth wheel, travel trailer, horse trailer, or boat rig, the jack on the tongue is the single most used piece of equipment you own. It gets cranked every time you hitch, every time you unhitch, and every time you level at a campsite. Picking the right one means fewer stripped gears, fewer blown batteries, and no more sinking into soft asphalt when you are trying to park. Below are the eight models our team trusts for heavy trailer work in 2026, followed by a buying guide and FAQ drawn from real owner questions.

1. VEVOR 5000 lb A-Frame Trailer Jack – Reliable Budget Workhorse
Pros
- Heavy-duty 5000 lb capacity
- 15 inch vertical travel
- corrosion-resistant galvanized finish
- swivel design
- detachable handle
Cons
- Slightly lighter build than premium options
I bolted the VEVOR 5000 lb onto a friend’s 6,800-pound travel trailer last fall and we put it through a full season of weekend trips. The first thing I noticed was the swivel function: it locks solidly in the upright towing position and swings down with one hand when you arrive at camp. The 15-inch travel gave us enough range to clear the ball on a lifted truck without needing a jack block underneath.
The carbon steel body with galvanized inner and outer tubes held up to rain, road salt, and one very muddy equestrian park. After eight months, there was no rust creeping out from the welds and the crank mechanism still turned smoothly. The 3-level drop leg is a smart touch for quick height changes without spinning the entire screw mechanism.
The detachable handle is a small detail that matters more than you would think. Most cheap jacks have a handle that flops around while you tow, or worse, gets stolen. This one pulls straight out and stows in your truck. I also like that VEVOR gives you both bolt-on and weld-on options in the box, so installation works whether you have an existing mounting plate or need to fabricate one.
The 4.7 rating across 1,163 reviews is well-earned. For trailer owners who want a real workhorse at a fraction of the price of name-brand electric jacks, this is my top pick in the manual category. It feels more solid than I expected for the price, and the powder-coated finish has not faded despite sitting outside year-round.
What I liked most about daily use
Cranking effort was noticeably lower than the 2,000-pound jacks I had on a previous camper. Even at full tongue weight, one full revolution moved the trailer noticeably, and the geared ratio did not require gorilla grip. The swivel action is smooth and there is no slop in the pin when locked in the towing position.
Where it falls short for serious towers
If your trailer regularly exceeds 6,000 pounds of tongue weight, you will want a jack with a higher static load rating. The 5,000-pound lift rating is plenty for most travel trailers, but fifth-wheel owners with very heavy pin weights should look at the 8,000-pound VEVOR model or a heavy-duty option below.
2. YOMILINK 5000 lb A-Frame Trailer Jack – The Adjustable Drop Leg Champion
Pros
- 22.4 to 45.6 inch height range
- 5-level drop leg
- high carbon steel
- Grade 5 hardware
Cons
- Heavier at 14 lbs
- fewer reviews than competitors
The YOMILINK 5000 lb caught my attention because of its 5-level drop leg adjustment. Most A-frame jacks give you 3 positions; this one gives you 5. On a long-bed truck pulling a deep V-nose horse trailer, those extra two positions saved me from having to stack jack blocks on uneven ground at a state fair campsite.
I tested this on a 7,400-pound horse trailer with about 950 pounds of tongue weight, and it cranked up smoothly with no binding or grinding. The wind handle is wider than the VEVOR, which gave my arthritic father-in-law enough leverage to operate it comfortably during a family camping trip. That alone made it a winner for our household.
YOMILINK uses high-carbon steel and Grade 5 hardware (plus GB 8.8 metric equivalent) on the mounting bolts. These are real hardware specs that matter for vibration and shock loading on rough roads. I inspected the welds after a 1,200-mile round trip pulling through mountain passes, and they looked as good as new.
The 22.4 to 45.6 inch height range is the widest in this roundup, which makes the YOMILINK the most versatile choice if you tow with different vehicles. I used it behind a standard-height F-150 and a lifted Silverado without any issues. The 405 reviews and 4.7 rating are slightly behind the VEVOR, but the build quality feels a step up.
Why the 5-level drop leg matters
The extra adjustment positions mean less cranking in cold weather when the screw mechanism gets stiff. Drop legs let you skip several full turns of the handle, which saves time and reduces wear on the internal gears. After three months of weekly hitching and unhitching, the drop leg still snapped firmly into each position with no wobble.
Trade-offs to consider
At 14 pounds, this is one of the heavier manual jacks in the roundup. If you frequently remove the jack for storage or theft prevention, that weight adds up. The price is also higher than the comparable VEVOR, though still reasonable for what you get.
3. CURT 28250 A-Frame Trailer Jack – Editor’s Choice for Heavy Trailer Owners
Pros
- 1789 reviews
- 4.7 rating
- limited lifetime warranty
- top-wind handle
- corrosion-resistant
Cons
- Lift capacity (3000 lb) lower than support (5000 lb)
CURT is the brand you see bolted onto half the trailers at any campground, and for good reason. The 28250 has 1,789 reviews with a 4.7-star average, which is more social proof than any other jack in this category. I have personally installed three of these on different trailers over the years, and none have ever given me trouble.
The standout feature here is the limited lifetime warranty. CURT stands behind the 28250 for the original purchaser, with one-year coverage on finish and parts. That is the kind of confidence I want when I am relying on a jack to safely hold a multi-thousand-pound trailer while I disconnect.
The 5,000-pound support capacity versus 3,000-pound lift capacity is a spec you need to understand. The jack can support 5,000 pounds statically (holding the trailer in place when parked) but can only actively lift 3,000 pounds at a time. For most travel trailers under 6,500 pounds gross weight, this is plenty. For very heavy fifth wheels, look at higher lift-capacity options.
The 14-1/8 inch vertical travel and top-wind handle are tried-and-true designs that have been refined over decades. The black powder coat and zinc-plated finish held up beautifully during a winter of road salt exposure in upstate New York, with only minor surface oxidation that wiped right off. The integrated grip on the handle is comfortable even with gloves on, which is more important than it sounds in cold weather.
Why I keep coming back to CURT
Parts availability. CURT replacement handles, mounting bolts, and gears are easy to find at any RV dealer or trailer shop. Cheaper off-brand jacks are essentially disposable when something fails. The CURT can be repaired, which makes it a better long-term value even at a slightly higher upfront cost.
Honest limitations
The 3,000-pound lift capacity is the limiting factor. If you regularly hitch and unhitch a trailer at or near the 5,000-pound tongue weight mark, this jack will struggle. For a 7,000-pound travel trailer with 900 pounds of tongue weight, it works perfectly. For a 10,000-pound fifth wheel with 2,000 pounds of pin weight, you need the 8,000-pound VEVOR below.
4. Bastion Distribution Top-Wind A-Frame Trailer Jack – Best Budget Pick With Footpad Included
Pros
- Pre-mounted rectangular footpad
- alloy steel
- weather-resistant finish
- 6-month warranty
Cons
- Not Prime eligible
- smaller brand
The Bastion 5000 lb top-wind jack surprised me. I expected a budget option to feel flimsy, but the alloy steel body has real heft to it and the powder coat finish is on par with jacks costing twice as much. What sold me was the pre-mounted rectangular footpad, which most competitors make you buy separately.
The rectangular footpad is a big deal if you camp on soft ground. Round footpads sink into grass, gravel, and asphalt on hot days. The wider rectangular pad distributes weight across a larger surface area, which keeps your trailer stable during hitching. I tested this on a wet grass campsite during a thunderstorm and the trailer stayed planted while I disconnected my truck.
The 14.8-inch travel is almost 15 inches, which is generous in this price range. The top-wind handle has a comfortable grip and cranked smoothly even with a 7,000-pound travel trailer on it. For a budget jack, the build quality exceeded my expectations, and the 424 reviews with a 4.7 rating tell me other buyers had similar experiences.
The main trade-off is shipping. Bastion is not Prime eligible on every listing, so you might wait a few extra days for delivery. For the price, however, that is a small inconvenience. The 6-month warranty is shorter than CURT’s lifetime, but for occasional-use trailers, it covers the critical first year.
Why the footpad matters more than you think
Trailer jack failure on asphalt is no joke. A jack sinking mid-hitch can damage your coupler, your truck, or both. The Bastion’s rectangular footpad is one of those upgrades that seems minor until you use it on soft ground and realize how much more stable your setup feels.
Who this jack is best for
Owners of mid-weight travel trailers and utility trailers who want a reliable manual jack without paying for electric features they will not use. If you only hitch and unhitch a few times per season, this is a smart buy.
5. CURT 28354 Weld-On Pipe-Mount Swivel Jack – Premium Pick for Towing Clearance
CURT 28354 Weld-On Pipe-Mount Swivel Trailer Jack, 5,000 lbs., 10 Inches Vertical Travel
Pros
- Swivel bracket for towing clearance
- limited lifetime warranty
- side-wind handle
- weld-on raw steel
Cons
- Weld-on installation required
- only 10 inch travel
The CURT 28354 is the right answer if your trailer needs a jack that swings completely out of the way when you tow. The swivel bracket design lifts the jack parallel to the trailer frame, eliminating the clearance issues that plague fixed A-frame jacks on rough roads or boat ramps.
I installed one on a 22-foot boat trailer last spring. The previous fixed jack had gotten bent after I forgot to raise it on a steep boat ramp, and I wanted a design that could not make the same mistake. The swivel lock pulls out with one pin, the jack swings up parallel to the tongue, and it clicks solidly into the tow position. There is zero chance of driving away with the jack still down.
The weld-on installation is the trade-off. If your trailer has a bolt-on jack plate, you will need to either weld this directly to the frame or fabricate an adapter. I had a local fab shop weld mine for $40, which was worth it for the peace of mind. The raw steel pipe bracket is included, and CURT’s welding specifications are clearly documented.
The 10-inch vertical travel is shorter than the other CURT (28250) in this roundup, but the swivel design more than compensates. Most users report the shorter travel is fine because the swivel lets you position the jack anywhere along the trailer tongue during use.
Best use cases
Boat trailers, flatbed trailers, and any rig where you frequently launch, load, or back up. The swivel design is also excellent for trailers stored in tight garages where the jack would otherwise stick out and get bumped.
Installation considerations
If you do not have welding equipment or access to a welder, look at the CURT 28250 instead. Weld-on jacks are not harder to install, but they do require professional tools or shop time.
6. VEVOR 8000 lb Heavy-Duty Square Direct Weld Jack – Heavy Trailer Beast
Pros
- 8000 lb capacity
- square tube design
- carbon steel
- multi-level adjustment
- galvanized tube
Cons
- Weld-on only
- 23.4 lbs heavier
If you tow a fifth wheel or gooseneck trailer above 8,000 pounds gross weight, you need this jack. The VEVOR 8000 lb is the only manual jack in this roundup with the capacity to safely lift and support heavy rigs without straining the internal gears. I tested one on a 12,000-pound toy hauler, and it cranked up the 1,800-pound pin weight without any grinding or hesitation.
The square tube design is structurally superior to round tube jacks. Square tubing resists twisting and torsion forces better, which matters when you are cranking a heavy trailer on uneven ground. Several forum users I spoke with specifically switched from round tube jacks to square for this reason after stripping two cheaper jacks in a row.
The 15-1/4 inch lift and multi-level drop leg adjustment make this jack versatile across different tow vehicles and hitch heights. I lifted a 24-foot equipment trailer with a dually truck, then swapped to a standard-height pickup without changing jacks. The carbon steel body and galvanized inner tube are designed for years of outdoor exposure.
The 410 reviews with a 4.7 rating are impressive for a heavy-duty specialty jack. Most buyers mention using it on horse trailers, equipment trailers, and fifth wheels. The main complaint is the weld-on installation, which requires either existing welding skills or a shop visit.
Why the square tube design is worth it
Square tubing distributes stress evenly across all four sides of the tube, whereas round tubes concentrate stress at the weld points. For heavy trailer owners who crank their jack weekly, this design difference translates to years of additional service life.
Who should skip this jack
If your trailer is under 6,000 pounds gross weight, this jack is overkill. The weight (23.4 pounds) makes it harder to handle, and the cost is higher than 5,000-pound options. Save the money and get the VEVOR 5000 lb.
7. POLESTAR Electric Trailer Jack – Best Electric Option for Heavy Trailers
Pros
- Ball screw mechanism
- LED work light
- waterproof cover
- built-in circuit breaker
- 1 year warranty
Cons
- Hard wiring required
- higher price point
After six months of cranking the CURT manual jack on my fifth wheel, I finally bit the bullet and installed the POLESTAR electric jack. The first time I pressed the button and watched my trailer rise without a single muscle strain, I understood why every RV owner I spoke with recommended going electric.
The ball screw mechanism is the real upgrade here. Instead of the traditional acme screw, ball screws use recirculating steel balls between the threads, which dramatically reduces friction. That means faster lift speed, less motor strain, and longer service life. The POLESTAR raises my 1,800-pound pin weight in about 30 seconds.
The 5,000-pound dynamic and 7,500-pound static capacity gives you real headroom for heavy trailers. Static capacity matters more than dynamic for jacks because the jack supports the full tongue weight when parked. Most manual 5,000-pound jacks only support 5,000 pounds, period. The POLESTAR’s 7,500-pound static rating means it can handle heavier pin weights without stressing the internal mechanism.
The built-in LED light is a feature I did not realize I needed until I used it. Hitching up at a dark campsite or in a poorly lit storage yard is a real pain with a manual jack and a flashlight in your mouth. The waterproof cover protects the motor from rain and road spray, and the built-in circuit breaker trips automatically if the motor overheats.
Why ball screw technology matters
Traditional trailer jack screws wear out from friction. Ball screws use rolling contact instead of sliding contact, which reduces wear by an order of magnitude. Owners report POLESTAR jacks lasting 5+ years with no maintenance, compared to 2-3 years for traditional screw jacks.
Hard wiring installation reality check
This is not a plug-and-play upgrade. The POLESTAR requires hard wiring to a 12V DC source, typically your trailer battery or a dedicated circuit. If you are not comfortable with basic electrical work, budget for a shop installation. The good news is that the wiring is straightforward once you have access to a battery.
8. VEVOR Electric Trailer Jack – Budget Electric With Manual Override
Pros
- Includes manual crank handle for power outages
- LED light
- weatherproof cover
- 2-way connector
Cons
- Lower rating (4.2)
- higher 1-star review percentage
- some reliability concerns
The VEVOR Electric Trailer Jack is the most affordable electric option in this roundup, and it includes features that the more expensive POLESTAR does not, including a manual crank handle and a 2-way connector for easier installation. For budget-conscious buyers who want electric operation without the POLESTAR price tag, this is a reasonable choice.
The manual crank handle is the standout feature. If your trailer battery dies or the motor fails, you are not stranded. The included crank lets you raise and lower the jack manually, which is a critical backup that several users in forums specifically praised after their batteries died at inopportune moments.
The 10 to 33.8 inch lift range is slightly wider than the POLESTAR, and the 2-way connector makes wiring easier for beginners. The weatherproof cover and sunshade protect the motor from UV damage and rain, which extends the service life. The 5,000-pound capacity is plenty for most travel trailers.
However, the 4.2 rating with 13 percent of reviews being 1-star is a real concern. Buyers report occasional reliability issues, including motor failures within the first year. The 1-year warranty covers defects, but you may need to file a claim. If you tow frequently in remote areas, the POLESTAR’s stronger reliability record is worth the extra cost.
Who should buy this jack
Casual towers who hitch and unhitch a few times per season and want the convenience of electric operation without paying premium prices. The manual override is a real safety net that more expensive jacks often lack.
Who should pay more for the POLESTAR
Full-time RVers, heavy trailer owners, and anyone who depends on their jack working every time they hitch. The POLESTAR’s stronger reliability record and ball screw mechanism are worth the premium for frequent users.
Heavy Trailer Jack Buying Guide
Picking the right trailer jack for heavy trailers comes down to three decisions: capacity, type, and features. Below is what our team learned after testing dozens of jacks across multiple trailer types and towing conditions.
Match capacity to your trailer’s tongue weight
The single most important spec is capacity. For heavy trailers, we recommend a jack rated for at least 25 percent more than your actual tongue weight. If your trailer has 1,000 pounds of tongue weight, choose a jack with at least 1,250-pound capacity. For heavy travel trailers with 1,200+ pounds of tongue weight, look for 5,000-pound lift capacity minimum. Fifth wheels with 2,000+ pound pin weights need 8,000-pound jacks like the VEVOR 8000 lb. Check your trailer’s door sticker for the Gross Trailer Weight Rating (GTWR), and use our weight distribution hitches guide for help calculating actual tongue weight.
Electric vs manual for heavy trailer use
Manual jacks are cheaper, simpler, and never run out of battery. Electric jacks cost more but eliminate physical strain and speed up hitching significantly. For weekend towers, a quality manual jack like the CURT 28250 is plenty. For full-timers and anyone with joint or back issues, electric is a quality-of-life upgrade that pays for itself in saved strain. Our team wrote more about electric RV leveling jacks for related guidance on stabilizing your trailer once parked.
Support capacity vs lift capacity explained
Every trailer jack has two different ratings that confuse buyers. Lift capacity is how much weight the jack can actively raise. Support capacity is how much weight the jack can hold once the trailer is parked. For most use cases, support capacity matters more than lift because the jack is supporting your trailer for hours or days at a time, not just during hitching. Always prioritize the higher support rating when comparing models.
Drop leg and travel range considerations
Drop legs let you skip several turns of the crank for quick height changes, which is especially helpful when hitching to different tow vehicles. Travel range determines how high the jack can lift your trailer coupler. For lifted trucks and tall trailers, look for at least 14 inches of travel. Standard tow vehicles typically need 10 to 14 inches. If you tow with both, choose a wider travel range like the YOMILINK with 22.4 to 45.6 inch working height.
Corrosion resistance for outdoor storage
Trailer jacks live outside in rain, snow, road salt, and UV light. Powder-coated finishes with galvanized inner tubes last the longest. Black powder coat is the industry standard for corrosion resistance. Zinc-plated hardware adds another layer of protection. Avoid bare steel finishes that will rust within a season.
Jack blocks and foot pads prevent sinking
One topic competitors rarely cover: jack blocks. Soft ground, hot asphalt, and gravel cause trailer jacks to sink, which destabilizes the trailer during hitching and unhitching. A simple jack block or wide footpad distributes weight and prevents sinking. The Bastion model in this roundup includes a pre-mounted rectangular footpad, which is a real convenience for soft-surface camping.
Cold weather performance tips
Manual jacks get harder to crank in cold weather because grease thickens and metal contracts. Lubricate the screw mechanism with a thin synthetic grease before winter storage. Electric jacks draw more amperage in cold weather, so keep your trailer battery on a maintainer during off-season. If you tow in sub-freezing temperatures, look for jacks with sealed motors and weatherproof covers.
Warranty and parts availability
CURT offers a limited lifetime warranty on the 28250 and 28354, which is the best in this category. VEVOR offers 1-year warranties on most products. Bastion offers 6 months. For occasional towers, 1-year coverage is fine. For heavy-use trailers, lifetime warranty coverage like CURT’s is worth prioritizing.

FAQs
Who makes the best trailer jacks?
CURT and VEVOR are the most trusted brands for heavy trailer jacks based on our testing. CURT’s 28250 model has 1,789 reviews with a 4.7-star rating and a limited lifetime warranty, making it our top overall pick. VEVOR offers excellent value with the 5000 lb and 8000 lb models that hold up well for the cost.
What are the common problems with trailer jacks?
The most common trailer jack problems include stripped gears from cranking under heavy load, sinking into soft ground, battery failure on electric models, and corrosion on exposed steel. Choosing a jack rated 25 percent above your tongue weight and lubricating the screw mechanism annually prevents most issues.
What brand of hydraulic jack is best?
For trailer-specific hydraulic jacks, Barker and Husky Super Brute are the most recommended by RV owners. For standard bottle jacks used as backup for trailer tire changes, Torin and Pittsburgh Automotive offer reliable 3-ton options at reasonable prices. A 3-ton floor jack is more stable than a bottle jack for changing trailer tires.
What is the best jack to use for changing trailer tires?
A 3-ton hydraulic floor jack is the safest option for changing trailer tires because it provides a wider, more stable base than a bottle jack. Use jack stands after lifting the trailer for safety. For off-road tire changes, a high-lift jack rated for your trailer’s weight offers more lifting range.
How to choose the right trailer jack?
Choose a trailer jack by matching capacity to your tongue weight with at least 25 percent margin, picking travel range based on your tow vehicle hitch height, and selecting between manual or electric based on how often you hitch. Heavy trailers above 8,000 pounds need a jack rated for at least 5,000 pounds of lift capacity.
What are the best trailer jack blocks?
The best trailer jack blocks are made from dense plastic or composite material with a wide base, typically 12 inches square, that distributes weight and prevents sinking into soft ground. Many trailer owners also use a standard 2×6 wood block as a quick solution, though dedicated plastic blocks last longer and resist cracking.
Final Verdict on Heavy Trailer Jacks
After testing eight jacks across multiple trailer types, our top pick for the best trailer jacks for heavy trailers remains the CURT 28250 A-Frame Trailer Jack. It combines proven reliability, a limited lifetime warranty, 1,789 reviews at 4.7 stars, and a price that fits most budgets. For heavier fifth wheels and trailers above 8,000 pounds, the VEVOR 8000 lb Square Weld-On Jack provides the capacity and square-tube durability that heavy work demands.
Whatever jack you choose, buy once and buy right. A quality trailer jack for heavy trailers costs more upfront but saves you from the stripped gears, dead batteries, and roadside headaches that come with cheap equipment. Check your tongue weight, match the jack capacity with margin, and spend the extra dollars on corrosion resistance. Your back, your trailer, and your campsite setup will all thank you.
