rv Slide Out Support Jacks - Adjustable 5000lb Trailer Supports

In this review of the rv Slide Out Support Jacks the bottom line is simple: these adjustable supports are for RV owners and weekend travelers who need a straightforward way to stop slide-out sag and add stability. The reviewer found the pair to be solidly built and easy to set up, delivering the primary benefit promised - reliable support for extended slide rails - with minimal fuss. For anyone tired of a drooping slide or extra movement while operating the room, these supports address that single biggest pain point effectively.

Key Features

• Adjustable Height: Each support adjusts from 19 in to 47 in, allowing you to match the jack length to the height of most slide-out frames for secure contact.
• High Load Capacity: Rated to hold up to 5,000 lbs per jack, they provide heavy-duty support to reduce sag and bending under load.
• U-Shaped Top: The U-shaped tops are designed to fit most slide-out rails, helping distribute pressure and stabilize the slide when extended.
• Durable Construction: Made from heavy-duty steel with a zinc powder-coating finish, the supports resist corrosion and stand up to repeated use.
• Tool-Free Setup: Supplied as a pair with no assembly required and incremental locking positions for quick, one-person height adjustment.
• Replacement Support: The product includes a quality assurance promise to replace failed parts, saving time and money for owners needing a warranty response.

Who It's For

These slide out supports are best for RV owners, travel trailer users, and seasonal campers who experience slide-out sag, excessive movement, or occasional bending of the slide rail. Installers who prefer a simple, no-assembly solution that can be adjusted by hand will appreciate the quick locking positions and the U-shaped top that suits common frame shapes.

Those who need an officially telescoping or powered stabilizer, a precisely swiveling head, or a product intended for structural repair rather than temporary support should look elsewhere. Also, buyers expecting a freely swiveling head may be disappointed since some users report limited swiveling motion.
