Yesland Trailer Stabilizer Jacks 2-Pack — Telescoping 11.4"–18" Adjustable RV Slide-Out Support, 1,000 lb Capacity Each

Yesland 2 Pack Trailer Stabilizer Jacks are adjustable telescoping support stands that help steady RV slide-outs and small trailers, each rated for a 1,000 lb static load and extending from 11.4" to 18".

These compact stabilizers are built to add rigid support under camper slide-outs, motorcycle trailers, overland trailers and small utility trailers. Constructed from heavy-duty steel with a zinc powder-coat finish, the pair ships ready-to-mount and includes an 11.8" steel rod that powers the telescoping adjustment. They’re intended to resist rust while delivering simple, tool-free height changes for on-site stabilization.

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

The telescoping design lets you change each jack’s length quickly using the included 11.8" steel rod handle. Turn the rod to raise or lower the inner tube until the desired height is reached, then secure it in the pre-drilled mounting position. No complex assembly is required, making it suitable for field adjustments.

• Adjustable range: 11.4" to 18" per jack
• Included jack rod: 11.8" steel handle for leverage
• Telescoping tubes allow fine incremental height control

What load and strength can I expect from each stabilizer?

Each stabilizer is rated with a static load capacity of 1,000 lbs and a lift capacity of 500 lbs, offering dependable support when slide-outs are extended or when loading gear. The steel construction and zinc powder-coating increase durability and resist corrosion from road and weather exposure. The telescoping junctions and plate footprint were designed to distribute weight and minimize wobble.

• Static load: 1,000 lbs per jack
• Lift capacity: 500 lbs per jack
• Bottom plate size: 3.4" W x 4" L for stable contact

How do I install and secure the stabilizers to my trailer?

Installation is straightforward: align the pre-drilled holes on the jack with your trailer’s mounting surface, then fasten using your own bolts or welding as preferred. The units are ready-to-mount out of the box, but the manufacturer suggests providing your own mounting hardware to match your trailer’s frame and surface. Once fastened, use the rod handle to set the support height and check for solid contact with the ground.

• Pre-drilled mounting holes—mounting hardware not included
• Compatible with bolt-on or welded installations
• Use the jack rod to fine-tune ground contact and stability

Will these stabilizers withstand outdoor use and corrosion?

The jacks are fabricated from heavy-duty steel and finished with a zinc powder-coat specifically to resist rust and corrosion from moisture and road salts. The finish lengthens service life, while the solid construction reduces flex under load. For extended longevity, periodic cleaning and inspection of welded or bolted areas is recommended.

• Heavy-duty steel construction for strength
• Zinc powder-coating protects against rust
• Minimal maintenance: inspect mounts and wipe clean occasionally

Who is this for: These Yesland stabilizer jacks are geared toward RV owners, overlanders, and small-trailer users who need quick, reliable support for slide-outs and cargo shifts. They suit people who want a compact, strong solution that’s easy to install and adjust—especially when bolting or welding to an even mounting surface. If you need heavy-duty stabilization without bulky permanent jacks, this two-pack offers portable, corrosion-resistant support designed for routine travel and campsite use.
