LUSHIH RV Slide Out Stabilizers
The LUSHIH stabilizers are designed for travel trailers with slide-outs, offering a 15″ to 26″ travel range and a 5,000 lb per jack capacity. Made from heavy-duty steel with a zinc powder coating, they resist rust and corrosion, making them suitable for varied climates. The triangular screw design and M18 nut provide stability, while the compact top dimensions fit most slide-out frames. A wood 2×4 on top is suggested to prevent trailered damage. Best for: mid-size trailers needing solid, rust-resistant support at moderate heights. Caution: use supplementary blocks on soft or uneven ground to prevent sinking.

The top block is constructed for strength, and the system can be raised or lowered with a power drill or a hand crank. Best for: campers needing quick, block-free setup and fast adjustment on larger RVs. Limitation: requires a drill for faster operation; cordless power is a must to maximize speed.

Buying Guide
- What load capacity do you need? If you operate large slide-outs or full-time RVs, aim for 20,000 lb total capacity across four jacks or more.
- How adjustable should height be? Most setups offer 19″–49″ or 20″–48″ ranges. Consider your typical campsite elevations and ground conditions.
- Is ease of use important? Power-drill aided systems save time, but may require access to a drill and power source.
- What ground conditions will you encounter? For soft ground, use leveling blocks and secure placement to prevent sinking or shifting.
- Does top design matter? Flat tops reduce the need for blocking but ensure frame compatibility with your slide-out rails.
