SKYFISH Slide-Out Support Jacks for RVs and Campers, 20–40" Telescoping Pair, 5,000 lb Each with Anti-Vibration Rubber Pad

These are a pair of adjustable SKYFISH LEADBRAND slide-out support jacks that stabilize RV, camper, and travel-trailer slide-outs from 20" to 40", each rated to 5,000 lbs and topped with an anti-vibration rubber pad.

When a slide-out sags, shifts in wind, or creates rattling metal contact, you need a compact stabilizer set that installs fast, holds heavy loads, and stops noise. The LEADBRAND Slide Out Support Jacks are hand-operated, zinc powder-coated steel stands that fold for storage, telescope between 20" and 40", and use a U-shaped top with an anti-vibration rubber mat to prevent metal-on-metal clanking while protecting the slide-out frame.

How do these jacks prevent slide-out sag and damage?

By bearing vertical load close to the slide-out rail, the jacks reduce bending forces on the frame and rails. They lock into position quickly and add support at the points where sag most commonly begins, reducing long-term wear.

• Each jack rated to 5,000 lbs; pair supports up to 10,000 lbs total.
• U-shaped top fits common slide-out frame widths and centers force.
• Anti-vibration rubber mat prevents metal contact and reduces movement noise.
• Folding handle telescopes bracket in under a minute per jack.

Will these work on soft ground and uneven surfaces?

The 5" diameter circular base spreads load to minimize sinking on grass, dirt, gravel, or sand. For very soft or uneven terrain, adding a wooden or concrete leveling block beneath the base increases stability and keeps the jack upright and effective.

• 5" round base distributes weight to resist sink-in.
• Recommended use of leveling blocks on very soft surfaces.
• Fold-flat design increases contact area and simplifies placement.
• Zinc powder-coating helps resist corrosion when used outdoors.

How fast and simple is setup and storage?

Setup is designed to be quick: unfold the handle, place the U-top under the slide-out frame, and crank the bracket up until it makes secure contact. Each jack takes under 60 seconds to place; no tools or assembly are required out of the box, and the folding handle lets the units stow compactly in tight compartments.

• No assembly — ready to use straight from the box.
• Folding handle raises bracket quickly and locks in position.
• Compact profile fits small storage bays and under-seat lockers.
• Simple manual operation eliminates hydraulic or electric failure points.

Are these durable enough for long-term outdoor use?

The jacks are built from heavy-duty steel and finished with a zinc powder coat to resist rust and abrasion during seasonal use. While the finish improves outdoor longevity, storing them indoors when not in use will extend service life the most.

• Heavy steel construction for high-strength support.
• Zinc powder coating reduces corrosion from weather exposure.
• Rubber anti-vibration pad protects slide-out contact points.
• Compact, rugged design withstands frequent deployment and storage.

Who is this for: RV owners, camper and travel-trailer enthusiasts, and Class A motorhome drivers looking to eliminate slide-out sag, reduce rattling, and add reliable vertical support during set-up or long-term storage. These jacks suit anyone who needs fast, tool-free stabilizing for residential-style slide-outs, bumper-mounted carriers, or temporary load support — especially when noise reduction and corrosion resistance matter.
