BYERNAUTO RV Slide-Out Support Jacks 2 PC — 5,000 lb Capacity, 20"–49" Telescoping Stabilizers

BYERNAUTO RV Slide Out Support Jacks are a pair of adjustable U‑shaped stabilizers that steady slide-outs and support up to 5,000 lbs each to prevent sagging and reduce movement.

When you park your RV, an unsupported slide-out can droop, vibrate, or flex — accelerating wear on rails and motors. These BYERNAUTO slide-out support jacks give fast, reliable reinforcement beneath the slide frame. Built from powder-coated steel, they combine a wide base, multiple lock positions and dual-drive operation so you can install and adjust them quickly, whether you prefer power or manual control.

How do these jacks attach and adjust to different slide-out heights?

Installation is straightforward with the supplied hardware and clear instructions. Each jack telescopes from 20" to 49" and locks into position with three indexed detents plus a threaded bolt for fine tuning.

• Adjustable height range: 20"–49" to fit most slide-out frames
• Three lock positions plus adjustable bolt rod for precise leveling
• Includes hardware and adapter socket for drill use
• Can be operated by a cordless drill (20–24V) or by hand crank

What load and ground conditions will these stabilizers handle?

Each BYERNAUTO jack is rated to support up to 5,000 lbs and has a 5" wide base plate to spread load and resist sinking on softer ground. The steel construction with rust-resistant coating stands up to outdoor conditions for longer service life.

• Rated capacity: 5,000 lbs per jack (for support, not for lifting the whole RV)
• 5" wide base prevents sinking and improves stability on dirt or gravel
• Powder-coated steel construction for corrosion resistance
• U-shaped top protects slide rails from bending and stress

Will these protect my slide-out mechanism and motor over time?

Designed specifically to brace the slide-out frame, the U-shaped top reduces sagging and limits side-to-side movement that can strain motors and rails. While not intended to lift the entire coach, they reduce wear by sharing load and stabilizing the slide during wind or uneven terrain.

• U-shaped cradle helps prevent rail bending and frame stress
• Reduces motor workload by limiting slide-out flex and sway
• Helps maintain alignment and extends component life through support
• Not a substitute for primary jacks or leveling jacks for lifting

How quickly can I set them up and switch between power and manual operation?

Setup is quick: mount the jacks under the slide frame using the included hardware, then raise to height with either the hand crank or the supplied drill adapter and a 20–24V cordless drill. The combination of rapid powered drive and a manual option gives speed and precise control where you need it.

• All mounting hardware and a drill adapter included for easy start-up
• Use a 20–24V cordless drill for fast extension; switch to hand crank for fine adjustments
• Clear instructions minimize installation time
• Two lifting options let you adapt in-the-field without extra tools

Who is this for? RV owners, full-time travelers and weekend campers who want to protect their slide-out rooms from sagging, vibration and premature wear will benefit from these BYERNAUTO slide-out support jacks. They are suited to most trailers, campers and motorhomes that require additional slide-out reinforcement, and for anyone who prefers a durable, adjustable stabilizer with both powered and manual operation.
