SKYFISH LEADBRAND Slide-Out Support Jacks 20-40" Pair — 5,000 lb Capacity, Anti-Vibration Rubber Top

SKYFISH LEADBRAND Slide Out Support Jacks are a pair of hand-operated stabilizers made to reduce sag, protect slide-out frames, and keep slide-outs steady during camping or storage. Each jack adjusts from 20" to 40" tall, features a U-shaped top with an anti-vibration rubber mat, and has a wide 5" circular base to resist sinking on soft ground. The zinc powder-coated finish improves corrosion resistance while the folding handle speeds setup and fits compact storage spaces.

How do these jacks protect my RV slide-out frames?

These supports take strain off the slide-out rails and reduce flex that causes long-term wear. By bearing load under the slide-out edge, they limit downward movement and reduce stress on factory mechanisms.

• U-shaped top cradles standard slide-out frame rails without metal-on-metal contact.
• Anti-vibration rubber mat prevents squeaks and absorbs small shocks from wind or movement.
• Each unit carries up to 5,000 lbs, and the set supports up to 10,000 lbs total for larger slide-outs.

Will these stabilizers work on soft or uneven ground?

The wide 5" diameter circular base spreads load to reduce sinking on grass, dirt, gravel, or sand. For very soft surfaces, using a wooden or concrete leveling block under the base increases footprint and stability.

• 5" base resists sink-in on common campsite surfaces.
• Use leveling blocks for muddy or extremely soft ground.
• Folding handle permits quick height adjustments to match uneven terrain.

Are these quiet and easy to set up?

Yes — the built-in rubber pad removes metal-on-metal contact, eliminating clanking and squeaking when the slide-out is bumped by wind or movement. Setup is designed for speed and simplicity with no tools required.

• Anti-vibration rubber mat prevents noise during small slide-out shifts.
• Folding handle raises the bracket quickly in under 60 seconds per jack.
• No assembly out of the box; compact storage-ready folding design.

What RV types and slide-outs are these compatible with?

The adjustable 20"–40" range and U-shaped top make these jacks suitable for most fifth wheels, travel trailers, and Class A motorhomes. They fit common slide-out frame widths and are supplied as a pair for proper support.

• Height adjusts from 20" minimum to 40" maximum to match a wide range of vehicles.
• U-shaped top fits standard slide-out rails; ideal for residential-size slide-outs.
• Pack of 2 — typical installation uses two jacks for balanced support under one slide-out.

Who is this for? These SKYFISH LEADBRAND Slide Out Support Jacks are intended for RV owners who want a durable, quiet, and easy-to-use solution for preventing slide-out sag and reducing wear on slide-out frames. They suit owners of fifth wheels, travel trailers, and Class A motorhomes who need fast setup, high load capacity (5,000 lbs per jack), and better stability on a variety of campsite surfaces. Store them in a compartment when not in use to prolong the zinc powder-coated finish and maintain top performance.
