Updated on · By the Tinker Jacks team

The best trolley jacks for 4x4 trucks and lifted vehicles include the Powerbuilt Biggie Smalls 2.5 Ton Off-Road Trolley for gravel and dirt driveways, the Maxority 2-Ton for keeping in the truck bed, and the Cat Wheelie Off-Road Trolley Jack for light 4x4s on cracked pavement.

  4. Which trolley jack should a 4x4 owner buy?

The best trolley jack for 4x4 owners is the Powerbuilt Biggie Smalls 2.5 Ton, with 4-inch wheels that roll over gravel and a saddle extension that reaches 20-1/8 inches. Pick the Liftmaster 3 Ton if your truck carries a tall lift kit, or the BIG RED T83006 when you need 3 tons for a full-size 4x4.

Most trolley jacks are built for flat garage floors and low sedans. A 4x4 asks more: the jack has to roll over gravel, slip under a raised axle and reach a jacking point that sits higher than a car's.

That changes what matters. Wheel size, top lift height and capacity count more than a low profile.

We compared seven jacks on those three points, plus handle storage and weight for anyone who carries a jack in the truck. Our score weighs specs, features and buyer feedback against what you're shopping for.

The split shows up in the numbers. Top lift height across this group runs from 11.8 inches on the Maxority to 21 inches on the Liftmaster.

Weight runs from 23.6 lb on the Cat to about 89 lb on the DNA Motoring. A jack that is light and short and one that is heavy and tall are built for different owners, and the order below reflects that.

If you want the widest view of the category first, our guide to the best floor jack covers how to choose one for a garage. For lighter SUVs and crossovers, the best floor jacks for SUVs keep things simple.

How we picked the best trolley jacks for 4x4s

We looked for jacks whose wheels, reach and rating match a lifted or off-road vehicle, not a sedan. Three specs decided most of the order, and two practical details broke the ties.

Wheel size decides where the jack works

A 4x4 often parks on gravel, dirt or a cracked driveway. Standard steel casters catch and sink on that ground.

The Powerbuilt and Cat models both run 4-inch wheels that roll over rough surfaces, so they climb onto a gravel driveway without fighting you. Steel-caster jacks like the DNA Motoring and BIG RED belong on concrete.

The difference is the footprint of the wheel, not just its size. A 4-inch wheel spreads the load over more ground and rolls over small stones and cracks instead of jamming against them.

A small steel caster digs in and stops, which is when owners drag the jack and strain the frame.

Top lift height has to clear your jacking point

Lifted 4x4s raise the frame and axle, so a jack with an 11-inch top height may not reach. The Powerbuilt with its saddle extension tops out at 20-1/8 inches and the Liftmaster at 21 inches.

The Maxority stops at 11.8 inches and the Jack Boss kit at 13.4 inches, which is fine for stock-height SUVs but short for a lift kit.

Look at the gap between those figures and a typical lifted axle. A 20-inch or 21-inch top gives you room to pump the handle without running the saddle into its limit.

An 11.8-inch top leaves a lifted truck untouched, no matter how hard you pump.

Capacity should leave headroom

Work out the load on one corner, then choose a jack rated above it. A 2-ton jack handles light 4x4s and crossovers, a 2.5-ton or 3-ton jack covers most trucks, and the 4-ton DNA Motoring takes the heaviest rigs.

A jack run at its limit wears faster and feels less stable.

The ratings in this group span 4,000 to 8,000 lb. That is the full width of the light 4x4 to heavy towing rig range.

Matching the rating to the corner weight, not the whole vehicle, is what keeps you from buying twice.

Handle storage and weight for truck-bed jacks

If the jack lives in the truck, the handle needs to stay with it. Padded spring clips on the Powerbuilt and Cat hold the bar in place.

Weight matters too: the Cat is 23.6 lb and easy to lift, while the DNA Motoring is around 89 lb and stays in the garage.

The 40 lb Powerbuilt and the 40.37 kg DNA Motoring sit at opposite ends of that question. A jack you can lift with one hand is more likely to come along on a trip, and a jack you cannot lift is more likely to stay where you park it.

The features that decided the ties

When two jacks scored close, the saddle extension broke the tie. The Powerbuilt and Cat both include one; the BIG RED reaches its 20-7/8 inches with an extra long saddle neck and no removable part.

A saddle extension adds reach only when you attach it, so it also gives you a lower starting height for the times you work on a lower vehicle.

The Powerbuilt takes the top spot for most 4x4 owners, and each pick below solves a different problem. Read the badge first, then the write-up for the trade-off against the others.

Powerbuilt Biggie Smalls 2.5 Ton Off-Road Trolley: Best for gravel and dirt driveways

Powerbuilt Biggie Smalls 2.5 Ton Off-Road Trolley, trolley jacks for 4x4 trucks and lifted vehicles
9.5/10Our score
  • 4-inch oversized wheels
  • 2.5-ton capacity
  • Saddle extension to 20-1/8 in
  • Handle storage clips

Big wheels roll over rough ground and the saddle extension gives lifted 4x4s the height they need.

See it on Amazon

Pros

  • 4-inch wheels handle uneven ground
  • Saddle extension adds about 3.75 inches of reach
  • Handle clips keep the bar with the jack
  • Compact frame stows in a truck bed

Cons

  • 40 lb is heavy to lift into a truck bed often
  • 2.5-ton rating limits it to lighter 4x4s and SUVs

The Powerbuilt is the pick for a 4x4 that lives on a gravel or dirt driveway. Its 4-inch wheels roll over loose ground that stops a standard steel caster, so you can move it into place without dragging.

The 2.5-ton rating covers compact SUVs and many light 4x4s. A saddle extension adds reach for taller vehicles, taking the top height from 16-3/8 inches to 20-1/8 inches.

That extra 3.75 inches is what gets the saddle onto a lifted truck's jacking point. Without the extension the jack starts at 4-3/4 inches and tops out at 16-3/8 inches, so it still slides under a stock-height axle.

Handle storage is a small but useful detail. Spring steel clips keep the bar attached, so it doesn't roll away in the bed or garage.

At 40 lb it's light enough to move around but heavy to lift into a truck bed often. The compact frame measures 11.5 by 24 by 7.5 inches and stows in a truck bed or a corner of the garage.

It carries a 1-year limited warranty.

Buy it for a 4x4 on rough ground where the saddle extension matters. Skip it if the corner load exceeds a safe margin below the jack's 5,000 lb total rating, so rigs over about 3,000 lb per corner at 1.5x headroom.

Maxority 2-Ton: Best for keeping in the truck bed

Maxority 2-Ton, trolley jacks for 4x4 trucks and lifted vehicles
9.3/10Our score
  • 2-ton capacity
  • Blow-mold carrying case
  • Swivel casters
  • Safety overload valve

A cased 2-ton jack that stays organized and travels easily, though its 11.8-inch top height limits lifted trucks.

See it on Amazon

Pros

  • Carrying case keeps the jack and handle together
  • Swivel casters move it in tight spaces
  • Built-in safety valve stops overloads

Cons

  • 11.8-inch maximum height is short for lifted 4x4s
  • 2-ton rating suits sedans and light pickups, not heavy rigs

The Maxority suits an owner who wants a tidy jack that travels in the truck and stays organized. Its blow-mold carrying case holds the jack and handle, so nothing rattles loose in the bed.

The 2-ton rating covers sedans and light pickups. Hydraulic operation lifts with little effort, and the swivel casters move the jack into tight spots on a garage floor.

A built-in safety valve stops overloads before they damage the jack. The alloy steel build is made to take frequent use, and the secure lift saddle holds the load steady while you work.

The limit is reach. Its top height is 11.8 inches, so it won't clear a lifted 4x4's frame.

The 2-ton rating also caps it at lighter vehicles. A stock-height crossover or a light pickup is its home ground.

The 90-day warranty is the shortest in this group, which is worth knowing if the jack will see hard use. For a cased jack at a light rating, it is the cleanest package here.

Buy it for a cased jack that stays organized in the truck. Skip it for a lifted 4x4 or a heavy rig, where the short reach and 2-ton rating run out.

Cat Wheelie Off-Road Trolley Jack: Best for light 4x4s on cracked pavement

Cat Wheelie Off-Road Trolley Jack, trolley jacks for 4x4 trucks and lifted vehicles
9.1/10Our score
  • 4-inch oversized wheels
  • 2-ton capacity
  • Saddle extension to 17-1/2 in
  • Powder-coated finish

The lightest big-wheel jack here, with a saddle extension that reaches 17-1/2 inches for compact 4x4s.

See it on Amazon

Pros

  • 23.6 lb is easy to carry and stow
  • 4-inch wheels roll on cracked pavement and dirt
  • Saddle extension adds 3 inches of lift
  • Handle clips keep the bar attached

Cons

  • 2-ton rating caps it at light 4x4s and crossovers
  • 6-inch minimum height needs clearance under low axles

The Cat Wheelie is the lightest big-wheel jack here at 23.6 lb. If you carry a jack in the truck for trailside fixes, that weight is the reason to pick it over the Powerbuilt.

Its 4-inch wheels handle cracked pavement and dirt, and the powder-coated finish resists corrosion. A saddle extension raises the top height from 14-1/2 inches to 17-1/2 inches, enough for many compact 4x4s.

Handle clips keep the bar attached. Without the extension it starts at 6 inches and reaches 14-1/2 inches, so a lifted axle needs the extra part.

The 2-ton rating suits light 4x4s and crossovers. Its 6-inch minimum height needs clearance under the axle, so it won't slide under a very low car.

For a full-size truck, the capacity and the 17-1/2-inch top height both fall short. It measures 8 by 21.25 by 6.62 inches and carries a 1-year manufacturer warranty.

If you want one jack for light 4x4s and the road, its weight is hard to beat.

Buy it for a light 4x4 and a jack you carry on trips. Skip it for full-size rigs or heavy 4x4s that need more than 4,000 lb of lift.

BIG RED T83006 3 Ton Trolley Jack with Extra Saddle: Best for heavy 4x4s and towing rigs

BIG RED T83006 3 Ton Trolley Jack with Extra Saddle, trolley jacks for 4x4 trucks and lifted vehicles
8.8/10Our score
  • 3-ton capacity
  • Extra long saddle neck
  • Lift range to 20-7/8 in
  • Single piston quick lift pump

A 3-ton jack with a long saddle neck that reaches 20-7/8 inches, built for full-size 4x4s and vans.

See it on Amazon

Pros

  • 3-ton rating covers full-size trucks and vans
  • 20-7/8-inch top height suits lifted 4x4s
  • Quick lift pump raises the saddle fast
  • Safety bypass prevents overloading

Cons

  • Steel casters are smaller than the off-road wheels here
  • No carrying case or handle storage clips

The BIG RED T83006 is the pick for full-size 4x4s, vans and towing rigs. Its 3-ton (6,000 lb) rating leaves headroom for heavy corners, and the extra long saddle neck reaches 20-7/8 inches without an extension.

That long neck saves time on tall vehicles: you pump less to get the saddle to the jacking point. A single piston quick lift pump raises it fast.

The safety bypass system stops overloading, and two large steel casters plus two 360-degree swivel casters move the jack on concrete. The handle is 24.5 inches long, which gives you good leverage on a heavy lift.

It doesn't have the off-road wheels of the Powerbuilt or Cat. On gravel, the smaller steel casters struggle.

There's also no carrying case or handle clip. At 36 lb it is lighter than the Powerbuilt, so it moves around the garage easily even though it lacks the rough-ground wheels.

For a heavy truck on a concrete driveway or garage floor, it's the strongest balance of reach and capacity, backed by a limited 1-year warranty.

Buy it for a full-size 4x4 or van on concrete. Skip it if your driveway is gravel or you need the jack to travel in the truck.

Liftmaster 3 Ton SUV High Lift Floor: Best for tall lift kits

Liftmaster 3 Ton SUV High Lift Floor, trolley jacks for 4x4 trucks and lifted vehicles
8.7/10Our score
  • 3-ton capacity
  • 21-inch maximum height
  • 19 cm minimum height
  • Alloy steel frame

The tallest reach in this group at 21 inches, made for trucks with big lift kits and raised chassis.

See it on Amazon

Pros

  • 21-inch top height clears tall lift kits
  • 3-ton rating for heavy 4x4s
  • Low 19 cm starting height slips under raised axles

Cons

  • May not fit under regular sedans or small cars
  • No saddle extension or handle storage

The Liftmaster is for the tallest trucks in the group. Its 21-inch maximum height is the highest here, so it reaches jacking points that stop the other jacks.

The 3-ton rating matches the BIG RED, and its 19 cm minimum height lets it slip under raised axles. If your 4x4 runs a big lift kit and sits well off the ground, this is the jack that gets there without an extension.

It lists fitment for cars, RVs, SUVs, tractors, trailers, trucks and vans.

Liftmaster says it's ideal for SUVs, vans and pickups, and warns it may not fit under regular sedans or small cars. That's the trade-off: it's built for height, not for low cars.

The alloy steel frame measures 24.41 by 7.87 by 7.87 inches, so it stows upright without much floor space. It also skips the saddle extension and handle storage the Powerbuilt and Cat offer.

Its 16.26 kg weight puts it in the middle of this group, and there is no case in the box.

Buy it for a 4x4 with a tall lift kit. Skip it if you also work on low cars, or if you want the handle to clip to the jack.

DNA Motoring Floor Jack 4 Ton: Best for the heaviest loads

DNA Motoring Floor Jack 4 Ton, trolley jacks for 4x4 trucks and lifted vehicles
8.5/10Our score
  • 4-ton capacity
  • Dual piston fast lift
  • Low 4.5-inch profile
  • Rubber-padded saddle

An 8,000 lb jack with a low 4.5-inch profile and 20 inches of reach, but its steel wheels and weight suit a garage floor.

See it on Amazon

Pros

  • 4-ton rating handles the heaviest 4x4s
  • Dual piston pump lifts quickly
  • Rubber saddle pad protects the axle
  • Overload valve stops damage

Cons

  • About 89 lb makes it a garage-only jack
  • Small steel casters bog down on gravel

The DNA Motoring takes the heaviest loads here. Its 4-ton (8,000 lb) rating covers rigs the 2- and 2.5-ton jacks can't, and the dual piston pump lifts quickly.

A low 4.5-inch profile helps it slide under axles even on a lifted truck. The rubber-padded saddle protects the axle from scratches, and an overload valve stops damage if you push it too far.

Large steel casters and 360-degree swivel casters keep it moving on a garage floor. The lifting range runs from 4.5 to 20 inches, so it covers low cars and lifted trucks in one jack.

Weight is the trade-off. At about 89 lb, it's a garage jack, not one you lift into a truck bed.

The small steel casters also bog down on gravel, so it suits a concrete slab. Use jack stands for any prolonged work, since the maker states it's designed for lifting only and must not hold a load for a long period.

For the heaviest rigs on concrete, the 4-ton rating is the reason to own it.

Buy it for the heaviest 4x4s and a concrete garage. Skip it for a truck-bed jack or a gravel driveway.

2T Hydraulic Floor Jack Combo with Two: Best for a first 4x4 tool kit

2T Hydraulic Floor Jack Combo with Two, trolley jacks for 4x4 trucks and lifted vehicles
8.3/10Our score
  • 2-ton floor jack
  • Two 2-ton jack stands included
  • Lift range to 13.4 in
  • Safety valve and vent plug

A starter kit pairing a 2-ton jack with two stands, but the 13.4-inch reach and 2-ton rating leave little room for lifted 4x4s.

See it on Amazon

Pros

  • Jack stands come in the box
  • Padded handle protects paint
  • Safety valve guards against overload
  • Mild steel frame with rust-resistant powder coat

Cons

  • 13.4-inch maximum height is short for lifted 4x4s
  • The maker says it isn't for pickups or big SUVs

The Jack Boss kit suits a first-time 4x4 owner building a tool set. It pairs a 2-ton floor jack with two 2-ton jack stands, so you get lifting and support in one box.

The jack lifts from 5.5 to 13.4 inches, and the stands run from 10.8 to 16.5 inches. For a stock-height 4x4 or a light pickup, that covers basic tire changes and brake work.

A safety valve and vent plug guard against overload, and the padded handle protects paint. The mild steel frame has a welded design and a red powder coat for rust resistance.

The limits show up on lifted 4x4s. A 13.4-inch top height won't reach a raised frame, and the maker says it isn't for pickups or big SUVs.

Its mild steel frame is durable but not built for the heaviest loads. For a light 4x4 and a first kit, though, the included stands are real value.

The kit counts three items in one box, and the stands mean you can lift and support the truck with one purchase.

Buy it for a light 4x4 and a starter kit with stands. Skip it for lifted trucks or heavy rigs, where the reach and rating run short.

What to check before you buy a 4x4 trolley jack

The right jack comes down to three numbers and one surface. Check your corner weight, your jacking point height and your driveway before you choose.

Measure your jacking point first

Park on level ground and measure from the ground to the jacking point on the frame or axle. Add a couple of inches of saddle travel.

If the number is near 20 inches, you need a saddle extension or the Liftmaster. A jack that tops out at 11 to 13 inches leaves no margin on a lifted truck.

Measure twice, because the jacking point and the axle are often at different heights. A frame rail sits higher than a differential, and a lifted truck can put a 4-inch gap between the two.

Pick the higher of the two points when you size the jack, and keep a couple of inches in reserve so the saddle is not at its limit.

Match capacity to the corner, not the whole truck

A 4x4 weighing 5,000 lb puts about 1,250 lb on each corner, but lifting one corner shifts weight. Aim for a jack rated at least 1.5 times the corner load.

A 2-ton jack covers light 4x4s, 2.5 to 3 tons covers most trucks and the 4-ton DNA Motoring handles heavy rigs. Running a jack at its limit wears it faster and feels less stable.

The jump from 2 tons to 2.5 tons is small on paper and large in practice. It is the step between a crossover and a light 4x4, and it is why the Powerbuilt sits at the top of this list for most owners.

Pick wheels for your driveway

Concrete is kind to steel casters. Gravel, dirt and cracked pavement are not.

If your 4x4 sits on loose ground, choose the 4-inch wheels on the Powerbuilt or Cat. On a concrete slab, the BIG RED and DNA Motoring roll fine and offer more reach or capacity.

For a garage-only setup, our roundup of the best floor jacks for the money covers value picks.

Decide if the jack travels with you

A jack in the truck bed needs handle storage and low weight. The Cat at 23.6 lb and the Powerbuilt at 40 lb both clip the handle in place.

The DNA Motoring is the heavy one here and better left at home. If you want a light jack for the road and a bigger one for the garage, an aluminum floor jack is the travel option.

Plan for jack stands either way

Every jack here is a lifting tool, and the DNA Motoring's own note makes the point plain: a jack must not hold a load for a prolonged period. Add stands to your kit before you crawl under the truck.

The Jack Boss combo includes two, and the other jacks pair with stands you supply. Chock the wheels on the ground and set the stands under the frame rails, not the axle, for the steadiest support.

Which trolley jack should a 4x4 owner buy?

The Powerbuilt Biggie Smalls 2.5 Ton is the best trolley jack for most 4x4 owners. Its 4-inch wheels roll over gravel, its saddle extension reaches 20-1/8 inches and its handle stays clipped to the frame.

For a full-size or towing rig, the BIG RED T83006 adds 3 tons of capacity and nearly 21 inches of reach. For a tall lift kit, the Liftmaster's 21-inch height is the pick.

And if you want the lightest big-wheel jack to carry on trips, the Cat Wheelie wins at 23.6 lb.

For a heavier rig on concrete, the DNA Motoring's 4-ton rating is the ceiling in this group, and the Maxority's case makes it the neatest light jack for the truck bed. The Jack Boss combo is the kit to start with when you want lifting and support in one box.

Start with your corner weight and jacking point height, then match the wheels to your driveway. That order keeps you from buying more jack than you need, or one that won't reach.

When you're ready to compare across the whole category, the best floor jack guide puts every type side by side.

Frequently asked questions

What capacity trolley jack do I need for a 4x4?

Pick a jack rated at least 1.5 times the weight you lift at one corner. A 2.5-ton or 3-ton jack covers most 4x4s, while a 4-ton model suits heavy rigs.

Check the axle weight rather than the whole vehicle's rating.

Why do off-road trolley jacks have big wheels?

Big 4-inch wheels roll over gravel, dirt and cracked pavement without digging in. Standard steel casters sink into soft ground and make positioning hard.

The bigger wheels also keep the jack steady on uneven driveways.

Will a trolley jack reach a lifted 4x4?

Only if its maximum height clears your jacking point. Lifted 4x4s often need 20 inches or more, so look for a saddle extension or a high-lift model.

A short jack with an 11- to 13-inch top height leaves no room on tall trucks.

Can I use a trolley jack on gravel?

Yes, with wide wheels and a flat, firm base under the jack. Off-road jacks with 4-inch wheels roll best on gravel and dirt.

Always chock the wheels and place jack stands under the frame before working underneath.

What is a saddle extension for on a trolley jack?

A saddle extension raises the lifting point when a truck sits high. Attach it for lifted 4x4s and remove it for lower vehicles.

It adds a few inches of reach, so check the height you need before relying on it.
