7 RV Stabilizer Jacks for Rock Free Parking at a glance
Why you can trust this guide
We compared these picks using verified manufacturer specifications, available manuals and documentation, current retailer listings, and patterns in owner feedback, alongside editorial research. We focus on measurable differences such as performance, capacity, usability, and build quality. Pickpedia does not present editorial research as laboratory testing, and we do not claim hands-on testing unless it was actually performed.
How we chose: We compared seven RV stabilizer jacks across capacity, height range, frame fit, and install hardware to sort scissor, stack, and specialty designs.
Stabilizer jacks stop the bounce and rock you feel when moving around a parked RV. They are not lifting jacks, so choosing the right type for your frame and clearance matters more than raw capacity numbers. Scissor jacks bolt under standard trailers, while stack jacks and I-beam models solve different problems.
Below we sort seven options by who each one fits, based on manufacturer specifications and features. We flag capacities, extended heights, and one real limitation per pick so you can match a jack to your rig instead of guessing. Reviewers repeatedly note that frame type and ground clearance decide fit.
Our top picks
LIBRA lists a 9,000 lb stabilizing capacity from thick 11-gauge steel with an electrophoresis coating, which the maker frames as strong corrosion protection. This four-pack ships ready to install, with sixteen mounting screws, a 9/16" socket, an 11/36" drill bit, and a drilling guide sticker. A 3/4" hex magnetic socket lets you run each jack with a power drill instead of cranking by hand. Extended height reaches 24" and retracts to 5". Like all stabilizer jacks, it is meant only for leveling and steadying, never for lifting or tire changes, so plan your parking accordingly.

Pros
- Thick 11-gauge steel with coated finish

Kohree offers a two-jack set rated to 7,500 lb, built from heavy-duty steel with an electrophoresis surface for corrosion resistance. You can turn the included crank handle by hand or fit the drill bit for faster raising and lowering, and the smooth tooth-gear arms keep extension vertical and straight. A wide bow-tie base spreads load to help hold trailers, motorhomes, and pop-ups steady. Maximum height is 24", retracting to 4". Since this is a set of two rather than four, most owners buy two boxes for full coverage, which is worth factoring into your order.

Pros
- Wide bow-tie base for load spread

OULEME rates each of these four scissor jacks to 6,500 lb and pairs them with an extra-wide base plate for steadier footing under load. The kit arrives ready to go, with a manual crank handle, a 3/4" drill socket, sixteen 3/8" mounting screws, and a printed instruction manual. Height adjusts across a wide range from 4" retracted to 24" extended, so it suits a variety of trailer frames. Chromate-plated bolts passed salt-spray testing per the maker for corrosion resistance. Capacity sits below the LIBRA set, so very heavy rigs may prefer a higher-rated option.
Capacity6,500 lb
Extended height24 in
Retracted height4 in
Set4 jacks, crank, socket, screws
Pros
- Extra-wide base plate for stability
- Complete out-of-the-box kit
- Salt-spray-tested plated bolts
Cons
- Lower capacity than heavy-duty sets
- Manual crank slower without a drill

Garvee designed this four-jack set specifically to support and steady RV slide-out rooms rather than the main frame. Rugged steel construction backs a stated 5,000 lb capacity per jack, and a tall adjustable range from 21.1" to 49" reaches slide-outs on uneven ground. A power drill or the included hand crank raises them quickly, and a magnetic hex socket ships in the box. The 5.1" by 1.2" top plate makes contact under the slide to cut sway and shake. These target slide-out sag, so they are a companion to frame stabilizers, not a replacement for them.
Capacity5,000 lb per jack
Height range21.1 to 49 in
Top plate5.1 x 1.2 in
Set4 jacks, crank, socket
Pros
- Purpose-built for slide-out support
- Tall height range for high slides
- Drill or crank adjustment
Cons
- Narrow top plate contact area
- Not a main-frame stabilizer

RVGUARD builds these stack jacks from cast aluminum that resists rust and corrosion, and a square base plus rubber pads keeps rigs from bouncing. Each supports up to 6,000 lb, and the set weighs under 40 lb total, so carrying and storing them is easy. When not in use they nest together to save space. You raise them by spinning a T-shaped handle, with wood or concrete blocks recommended underneath for taller setups. Height adjusts only from 11" to 17", so the maker recommends them for lower-to-the-ground rigs rather than trailers sitting high off the pavement.
Capacity6,000 lb
Height range11 to 17 in
MaterialCast aluminum
Set weightUnder 40 lb
Pros
- Light and nests for storage
- Rust-resistant cast aluminum
- Rubber pads cut noise and bounce
Cons
- Short height range
- Often needs blocks underneath

This OULEME stack-jack set is cast from premium-grade aluminum that shrugs off rust and corrosion, with each stand rated to a stated 7,900 lb. The pack includes four nuts and four cushion rubber pads that steady the rig and cut noise and wear while parked. Height adjusts from 11" to 17", matching the low profile of typical stack jacks. As with other stack designs, the limited height range means these suit lower rigs, and taller trailers will likely need blocks stacked beneath to reach a usable contact point.
Capacity7,900 lb
Height range11 to 17 in
MaterialPremium aluminum
Set4 jacks, nuts, rubber pads
Pros
- High stated capacity for a stack jack
- Rust-resistant aluminum build
- Rubber pads reduce noise and wear
Cons
- Short 11 to 17 in range
- Taller rigs need extra blocks

Safoner takes a different approach, targeting side-to-side sway so the RV feels solid when you walk, cook, or relax inside. Thick high-strength aluminum handles outdoor use, and seven adjustment positions let you fine-tune height across different terrain. A heavy-duty ratchet strap adds tension between the two legs to lock down lateral movement, and a carry bag holds everything for transport. This model fits only rigs with exposed I-beams on both sides and needs at least 17" of ground clearance, with adjustable height up to 35", so it will not work on skirted or low-frame trailers.
Adjustment7 height levels
Max heightUp to 35 in
Clearance needed17 in minimum
Includes2 legs, ratchet strap, bag
Pros
- Ratchet strap targets side sway
- Seven precise height levels
- Lightweight aluminum with carry bag
Cons

What to look for
Scissor jacks vs stack jacks
Scissor jacks bolt permanently under the frame and fold flat when retracted, which suits standard trailers. Stack jacks are portable stands you place manually, better for low rigs and quick storage. Match the type to your frame before comparing capacity numbers.
Capacity is for steadying, not lifting
Every jack here is rated for stabilizing and leveling only. The listed capacity describes how much load it holds steady, not how much it can raise. Never use a stabilizer to change a tire or support full vehicle weight off the ground.
Check your ground clearance
Height range decides fit more than anything. Stack jacks reaching 11 to 17 inches suit low campers, while slide-out and I-beam models need much taller clearance. Measure from your frame to the ground before ordering.
Install and operation
Scissor jacks need drilling into the frame, so most sets include screws, a bit, and a guide sticker. A power drill with a hex socket speeds raising and lowering, though a hand crank works if you have time. Rubber pads help cut noise on hard surfaces.
Frequently asked questions
Can these jacks lift my RV off the ground?
No. Every stabilizer jack here is built for steadying and leveling only. Owners and makers both warn against using them to lift the rig or change tires, since that risks failure and injury.
How many jacks do I need?
Most trailers use four, one near each corner. Two-packs like the Kohree set cover one end, so buy two boxes for full coverage. Slide-out and I-beam models are added on top of corner jacks.
Do I need a power drill?
Not required, but it helps. Sets with a hex socket let a drill raise and lower jacks quickly, while a hand crank does the same job more slowly. First-timers often start with the crank, then switch to a drill.
What is the difference between steel and aluminum jacks?
Steel scissor jacks tend to carry higher stated capacities and bolt to the frame. Cast aluminum stack jacks resist rust, weigh less, and store compactly, but usually have a shorter height range for lower rigs.
Will scissor jacks fit any trailer?
They fit most standard frames but require drilling to mount. Rigs with exposed I-beams or tall clearance may need the I-beam or slide-out styles instead. Check your frame type and clearance first.
How do I stop my slide-out from shaking?
Dedicated slide-out support jacks like the Garvee set place a plate under the extended room to cut sag and sway. They work alongside corner stabilizers rather than replacing them.
Do stabilizer jacks prevent all movement?
They greatly reduce bounce and rock but will not eliminate every bit of motion. Reviewers note that a level pad, chocked wheels, and firm ground all help the jacks do their job.
Should I put anything under the jacks?
Yes, on soft or uneven ground. Blocks of wood or concrete under stack jacks improve reach and footing, and rubber pads reduce noise and protect surfaces.
The verdict
LIBRA 9K lb HD 24" RV Trailer Camper Stabi...
9.2/10
For most trailers the LIBRA four-pack stands out as our top pick, pairing high stated capacity with a complete drill-ready install kit. Choose the OULEME set if you want everything boxed for a first install, or the Kohree pair to cover one end. Low rigs are better served by the RVGUARD aluminum stack jacks. For slide-out sag pick Garvee, and for I-beam sway control the Safoner strap system fits high-clearance frames.
