RV Slide Out Support Jacks Adjustable 15ft to 35ft - Heavy-Duty

In this review the AUH RV slide out support jacks are evaluated as an affordable, heavy-duty option for campers and travel trailers that need extra slide-out stability. The biggest reason to buy is straightforward: these jacks provide immediate, solid support for slide-outs with a simple installation process and a universal U-shape bracket that fits a wide range of RV slide-out supports. For owners who want to remove wobble and protect slide mechanisms without complex tools, these jacks offer practical value and long-term corrosion resistance.

Key Features

• Adjustable Height: The jack adjusts from 15.1' to 35.4' to suit many slide-out clearances and placement needs.
• Heavy-Duty Construction: Heavy alloy steel tubes and a solid circular base deliver a stable platform that reduces movement under load.
• Universal U-Shape Plate: The 5.1 by 3 in u-channel bracket and 5 in circular base provide secure positioning for common RV stabilizer bars.
• Corrosion Resistance: Zinc powder coating protects the steel from rust, extending usable life in outdoor conditions.
• Simple Installation: The two-step setup uses a lock pin and a wrench to quickly set height and final bolt adjustment without specialized tools.
• Two-Pack Convenience: The package includes two jacks so one pair is ready to install under a single slide-out for balanced support.

Who It's For

This product is aimed at RV and trailer owners who want a straightforward, mechanical solution to reduce slide-out movement. It suits travel trailer and fifth-wheel owners, as well as those with utility trailers, pop-up campers or small trucks that use external slide support points and need a compact, transportable option.

Those who should look elsewhere include owners who need a motorized or hydraulically actuated support system, and anyone requiring a capacity rating higher than the stated application or a bespoke mounting solution beyond the U-channel bracket. Also consider dedicated leveling systems if you require automated or remote adjustment.
