LUSHIH RV Slide Out Support Jacks Review
- Brand: LUSHIH
- Capacity: 5,000 lbs per jack
- Travel Range: 15″ to 26″; Working Range: 11″
- Construction: Heavy-duty steel with zinc powder-coating
- Top design: U-shaped top fits most slide-out frames; includes guidance to protect trailer tops
Best for budget-conscious campers who want solid, single-reserve stability on standard travel trailers. The 5,000-lb per-jack capacity provides reliable support for most mid-size rigs. The zinc coating helps resist rust in variable weather. A caution: consider adding a wood 2×4 topper to protect the slide-out frame during setup.
Kohree RV Slide Out Supports Jack (Flat Top)
- Brand: Kohree
- Top Design: Upgraded flat top with no extra blocks needed
- Height Range: 20″ to 49″
- Operation: Quick-rise via power drill or hand crank
- Includes: Block for drill compatibility and ergonomic handle
Best for RVers who value fast, tool-assisted setup and a flat top that eliminates the need for wooden shims. The flat-top design provides steadier contact with the slide-out beam. Limitations: use a drill or crank safely on uneven ground and ensure the drill battery is charged for smooth operation.
RVSHARK Slide Out Jacks Set of 2 (6000 lbs)
- Brand: RVshark
- Capacity: 6,000 lbs total (2 jacks)
- Operation: 20″-49″ height, power drill or handle
- Materials: Alloy steel and galvanized tubes
- Feature: Dual lift modes for flexible setup
Best for larger trailers or campers where extra margin is helpful and where two-jack systems are enough for stabilization. The dual lifting modes enhance adaptability, though users should verify compatibility with their slide-out frame and surface conditions. Caution: install on level ground or use blocking on soft surfaces to prevent sinking.
Kohree Set of 2 RV Slide Out Supports (2 Jacks)
- Brand: Kohree
- Capacity: 5,000 lbs per jack
- Height Range: 20″ to 49″
- Operation: Drill-assisted rise/fall or hand crank
- Includes: Crank handle and socket for drill
Best for mid-size RVs needing two jacks with quick drill-assisted operation. The 20″-49″ range supports a broad ground clearance spectrum. This option emphasizes ease of use and a complete accessory kit. Limitation: ensure the surface is firm to avoid settling under load.
RVSHARK 6000 Lbs Slide Out Jacks (2-Pack)
- Brand: RVshark
- Capacity: 6,000 lbs total with two jacks
- Height Range: 20″-49″
- Operation: Power drill or handle; 3-level adjustable base

Best for RVs requiring extra load capacity and reliable stability in varied wind and ground conditions. The 6,000-lbs total limit offers a safety margin for larger rigs. Caution: ensure secure anchoring on soft ground and inspect for corrosion in coastal areas.
Buying Guide: Key Purchase Considerations
- Weight capacity per jack: Match to your trailer’s unloaded weight and expected loads during setup. High-capacity options reduce sway and bounce on larger rigs.
- Height adjustment range: Ensure the 20″–49″ or 20″–49″ spec covers your ground clearance and the typical height of your trailer when extended.
- Top design and contact surface: Flat tops or U-shaped tops influence contact stability with slide-out frames. Flat tops reduce the need for extra blocks.
- Operation method: Drill-assisted or manual cranks—consider the speed, convenience, and battery reliability for quick setups at campsites.
- Materials and finish: Steel construction with protective coatings (galvanized or zinc-coated) improves rust resistance in humid or coastal settings.
- Number of jacks: Two-jack vs. four-jack configurations affect stability for longer slides and larger RVs. More jacks can reduce sway but require a larger footprint and setup time.
- Ground conditions and blocking: Hard surfaces may need little or no additional blocks, while soft grass or mud often requires back-up blocks or leveling pads.
Frequently Asked Questions
- What should I consider when choosing slide out supports for a travel trailer?
Look at per-jack capacity, height range, and whether you prefer drill-assisted or manual operation. Also consider the number of jacks and compatibility with your slide-out frame. - Are four-jack sets necessary for my RV?
Four-jack sets provide uniform support and reduce bounce on large fifth wheels or full-time RVs. For smaller trailers, two jacks may be sufficient. - Can I use these on uneven ground?
Use leveling blocks or concrete pads to improve stability on uneven or soft surfaces and avoid sinking. - Is drill-assisted adjustment safer than a manual crank?
Drill-assisted lifting speeds up setup and can reduce effort, but ensure you follow manufacturer safety instructions and use proper drill bits and battery care. - Do these jacks affect slide-out operation during travel?
They are designed to stabilize when parked. Ensure jacks are retracted or secured before driving to prevent interference with travel. - How do I prevent rust and corrosion on slide out supports?
Choose models with protective coating and store in dry conditions after use to extend life in humid or coastal environments.
