LUSHIH RV Slide Out Support Stabilizer Jacks 2-Pack 15"–26" Adjustable, 5,000 lb Zinc-Coated

LUSHIH RV Slide Out Support Trailer Stabilizer Jacks are a pair of heavy‑duty, adjustable supports rated at 5,000 lb each, built to stop slide‑out sway and add steadiness to parked trailers.

If your camper or travel trailer has a slide‑out that moves or vibrates when people walk inside, these adjustable stabilizer jacks are designed to anchor the slide section to the chassis and reduce that motion. Constructed from thick steel with a corrosion‑resistant zinc powder finish, the pair extends from 15" to 26" with an 11" working range and includes a U‑shaped top to align with common slide‑out frames.

How do these jacks attach to my RV slide‑out?

The stabilizers are meant to secure to a solid part of the trailer frame such as a rail where the U‑shaped top can sit beneath the slide‑out structure. Position the bracket so the top plate makes stable contact and use the folding handle to raise the jack until it meets the slide‑out support bars.

• Attach to a frame rail wide enough for the U‑shaped top (5.94" x 2.95" x 0.9").
• Raise from the lowest setting and lift slowly to the required height.
• Place a 2x4 across the top if you want additional surface protection.

What load and size limits should I know before using them?

Each jack is rated for a maximum lift capacity of 5,000 lb (2,267 kg) and a travel range of 15" to 26" with an 11" working range. They are designed to stabilize and prevent rocking of a parked slide‑out, not to raise the trailer off its wheels or to act as primary leveling jacks.

• Travel range: 15"–26"; working range: 11".
• Max lift per jack: 5,000 lb (use as stabilizers, not wheel lifting jacks).
• Do not use to lift trailer off tires or for final leveling.

How durable and weather resistant are these stabilizer jacks?

Fabricated from heavy‑gauge steel and coated with a zinc powder finish, the jacks resist rust and stand up to outdoor use. The threaded screw and M18 nut are matched for a triangular engagement that helps maintain secure adjustment over time.

• Zinc powder‑coated finish for corrosion resistance.
• Triangular threaded screw with M18 nut for reliable stability.
• Solid steel construction to handle repeated use and road exposure.

Who is this for: LUSHIH Slide Out Support Trailer Stabilizer Jacks are ideal for RV owners, families and boondockers who want a simple, robust solution to stop slide‑out wobble while parked. They suit travel trailers and campers with compatible frame rails and owners who understand these jacks are supplemental stabilizers — not primary leveling devices or lifting jacks. If you need a durable pair of supports that install quickly and resist corrosion, these jacks offer a practical way to improve comfort inside a parked trailer.
