Best Trailer Stabilizer Jacks
Compare frame-mounted scissor jacks and portable supports by extension range, mounting requirements and campsite setup—not inflated capacity claims.
Compare Current OptionsTrailer movement when someone walks inside is a different problem from getting the trailer level. Stabilizers are installed after the trailer is parked, chocked and leveled; the useful comparison is how each design reaches a stable contact point without overloading the frame or leaving hardware exposed during travel.

01 Quick picks by setup need
These choices cover distinct mounting and operating needs. The stated capacities are manufacturer ratings for the listed models, not permission to lift the trailer.
A conventional frame-mounted scissor stabilizer for trailers that need a short collapsed profile.
The longer-extension BAL alternative suits a trailer that parks on variable-height pads while still requiring a low stored profile.
A scissor stabilizer with a double-nut drive and a wide footpad, useful when repetitive hand cranking is the biggest annoyance.
A removable set for owners who do not want to permanently attach scissor jacks to the trailer frame.
02 Compare extension, not just ratings
Measure the collapsed clearance and working ground gap before selecting a model. A larger static rating cannot fix an incompatible mounting position.
| Model | Format | Published capacity | Height range | Best reason to choose |
|---|---|---|---|---|
| BAL 24010 Deluxe 24-inch Scissor Jack | 24-inch class | 7,500 lb static rating | 4 to 23.75 inches | Best for compact mounting |
| BAL 24013 Deluxe 30-inch Scissor Jack | 30-inch class | 7,500 lb static rating | 4 to 30 inches | Best for higher ground clearance |
| Ultra-Fab 48-979006 24-inch Scissor Jack | 24-inch class | 6,500 lb per jack | 4.75 to 24 inches | Best for faster manual setup |
| Ultra-Fab 48-979004 Stacker Jacks (4-pack) | Portable stacker | 6,000 lb per jack | 11 to 17 inches | Best portable support |
03 Model-by-model tradeoffs
Each option below is identified by a specific manufacturer model or pack SKU, rather than an interchangeable generic listing.
BAL 24010 Deluxe 24-inch Scissor Jack
A conventional frame-mounted scissor stabilizer for trailers that need a short collapsed profile.
What stands out: The manufacturer identifies this as a single jack without handle or hardware; plan the complete installation rather than assuming a ready-to-bolt kit.
Who it suits: Check available frame points and whether your trailer has room for the 23.75-inch extension.
A defined retracted dimension and a manufacturer-published static rating.
You must source suitable mounting hardware and an operating handle separately.
Ownership tradeoff: Inspect fasteners and the screw mechanism periodically; static rating does not make it a lifting jack.
Check PriceBAL 24013 Deluxe 30-inch Scissor Jack
The longer-extension BAL alternative suits a trailer that parks on variable-height pads while still requiring a low stored profile.
What stands out: BAL lists a 4-inch collapsed height and 30-inch extension for the single 24013 unit.
Who it suits: Measure the gap between frame mounting point and ground at real campsites; choose longer travel only if needed.
A broad extension range with the same published static capacity class as the shorter BAL.
A single replacement component is not necessarily a complete installation package.
Ownership tradeoff: Keep the jack clear of road debris in the retracted position and verify bolt or weld mounting guidance.
Check PriceUltra-Fab 48-979006 24-inch Scissor Jack
A scissor stabilizer with a double-nut drive and a wide footpad, useful when repetitive hand cranking is the biggest annoyance.
What stands out: Ultra-Fab specifies a 4.5-by-9-inch footpad and describes its double-nut drive; drill operation requires an appropriate compatible adapter.
Who it suits: Choose it when the frame and storage clearance suit the jack and you want a standard scissor layout.
Documented large footpad and a clearly identified single-unit SKU.
The single-pack listing should not be confused with a two-pack or an included drill adapter.
Ownership tradeoff: Use controlled torque and follow the maker’s mounting and operating instructions.
Check PriceUltra-Fab 48-979004 Stacker Jacks (4-pack)
A removable set for owners who do not want to permanently attach scissor jacks to the trailer frame.
What stands out: Ultra-Fab documents die-cast aluminum stacker jacks and an 11–17-inch adjustment range; the 48-979004 identifier is the four-pack.
Who it suits: Confirm solid designated contact points and sufficient ground-to-frame distance before choosing portable stands.
Compact stackable storage and no permanently exposed jack assembly.
The limited height range and separate setup at each stop are real constraints.
Ownership tradeoff: These are for stabilization, not raising the trailer or replacing rated vehicle stands.
Check Price04 Seven checks before installation
Use these checks before ordering and again before your first campsite setup.
- Separate leveling from stabilizing: Level with the proper trailer equipment first; do not attempt to correct side-to-side level by cranking a stabilizer.
- Chock wheels and secure the trailer: Keep the trailer immobilized before positioning or extending any support.
- Measure the true mounting gap: Check both travel clearance and distance to the ground at typical parking sites.
- Verify frame attachment locations: Follow the trailer and jack manufacturers’ mounting guidance; do not drill structural members without authorization.
- Read the rating correctly: A static support figure is not a trailer-lifting rating and must not be multiplied into a lifting claim.
- Confirm included components: Single replacement jacks may omit mounting hardware, handle, adapters or pads.
- Inspect contact and retraction: Use stable ground or approved pads, avoid excessive extension and retract fully before towing.
05 Choose the right stabilizing system
Already have factory scissor jacks? Replacing one damaged unit with a compatible height and mounting footprint is usually simpler than changing jack type. Confirm fastener spacing and load path rather than selecting by capacity alone.
Camp on uneven sites? Measure the maximum actual frame-to-ground gap; the BAL 30-inch option reaches farther than the 24-inch variants, but greater travel is useful only when the mounting geometry supports it.
Do not want permanent hardware? Portable stacker jacks avoid a frame-mounted mechanism, but you must carry, position and retrieve them every stop. Their 11–17-inch range makes measurement especially important.
Need less sway rather than a new jack? First inspect existing stabilizers and contact points. Additional bracing may address movement without replacing sound jacks; do not confuse bracing with leveling capacity.
06 Frequently asked questions
Can stabilizer jacks lift a travel trailer?
No. These products are selected for stabilizing a parked trailer. Use equipment specifically rated and approved for lifting or leveling when those operations are required.
Is a 7,500-pound static capacity a trailer weight rating?
No. It is a manufacturer-specified static capacity for a particular jack, not a statement that the jack can lift a 7,500-pound trailer or support the entire trailer by itself.
Should I choose a 24-inch or 30-inch scissor jack?
Measure the available mounting clearance and the ground distance where the trailer normally parks. The longer jack provides more extension, but only if its collapsed profile and mounting arrangement fit.
Are portable stacker jacks better than mounted scissor jacks?
They solve a different problem. Stacker jacks can be removed and stored, while scissor jacks remain attached for faster repeat setup. The Ultra-Fab stackers listed here adjust only from 11 to 17 inches.
Do I need pads under stabilizer feet?
Use the surface and support arrangements specified by the manufacturer. On soft or uneven ground, appropriate pads may help distribute contact pressure, but they do not increase the jack’s rating.
Can I use a cordless drill to extend scissor jacks?
Only if the jack and compatible adapter permit it. Apply controlled torque and stop at proper ground contact; power tools can damage mechanisms when overdriven.
07 The practical bottom line
Buy for geometry and attachment first. A 24-inch scissor jack may be sufficient on a low frame, while a 30-inch design offers extra reach for a higher mounting point. Portable stackers remove the permanent-mount requirement but add setup steps. Always level and chock first, then use stabilizers only within the manufacturer’s instructions.
