RV Slide Out Support Jacks 15-37in Heavy Duty Stabilizers - 5,000 lb

In this review of the RV Slide Out Support Jacks, the bottom line is simple: these stabilizers are for RV and travel trailer owners who need a strong, no-frills way to steady slide outs when parked. The set includes two heavy duty jacks that extend from 15in to 37in and are rated to support up to 5,000 lb each, so the primary reason to buy is solid load capacity combined with a durable zinc powder-coated steel construction that resists rust.

Key Features

• Adjustable height: The 15in to 37in range lets users position the jack to match common slide out clearances and leveling block stacks.
• High load capacity: Each jack is rated to support up to 5,000 lb, providing confidence when stabilizing large or heavy slide outs.
• Durable construction: Heavy duty steel with a zinc powder-coating helps the jacks resist corrosion and extends service life outdoors.
• Stable foot diameter: The 5in diameter foot spreads load on blocks or ground to reduce sinking on softer surfaces.
• Pair packaging: Two jacks come in the package, giving the pair needed for typical single slide out support without buying multiples.

Who It's For

This set is best for RV, camper and travel trailer owners who frequently extend slide outs and want a robust, simple stabilizer that can handle heavy loads and outdoor conditions. The jacks suit owners who use concrete or wooden leveling blocks to create a stable contact surface and who value corrosion resistance for long-term storage and use.

Owners seeking a precision leveling system, integrated mounting hardware, or micro-adjustment without blocks should look elsewhere; the product is a practical stabilizer rather than a full service leveling jack and relies on block support for best performance.

Pros & Cons

Pros

• Heavy duty steel and zinc powder-coating improve longevity and resistance to rust.
• High 5,000 lb per jack rating offers substantial support for large slide outs.
• Wide 5in foot and adjustable 15in to 37in range make placement versatile with blocks.
• Comes as a 2 PCS set, ready to add to camper accessories without extra purchases.

Cons

• Some users report mixed results with tightening and absolute flatness, so extra care and blocks are recommended for optimal stability.
