SUNSHINE FARMRE RV Slide Out Supports Stabilizer Jacks 16"–36" Adjustable, 2-Pack, 5,000 lb Capacity

SUNSHINE FARMRE RV Slide Out Supports are adjustable stabilizer jacks (16"–36") designed to prevent slide-out sag and add solid support for campers and travel trailers.

When you park your RV, the extended slide-outs can develop sag or sway that stresses frame rails and hardware. These heavy-duty support jacks attach under the slide-out and hold it level, reducing movement and protecting the mechanism. Built from thick steel with a zinc powder finish and a newly designed spiral shaft, each jack stands up to demanding use while resisting rust.

How do these supports stop slide-out sag and movement?

The stabilizer jacks create a vertical support point beneath the slide-out rail, sharing load and preventing the center of the slide from drooping. By removing the unsupported span, they lower stress on rail welds, rollers and seals and reduce lateral sway that you can feel inside the RV when walking.

• Rated to support up to 5,000 lb per jack for robust load-bearing.
• Hexagonal diamond bases resist sinking on soft ground and increase contact area.
• 5.3" U-shaped top fits most slide-out frames for secure seating.
• New spiral design minimizes rattling and self-tightens under load.

How easy is it to install and adjust these slide-out supports?

Installation requires no assembly — the jacks are ready to use out of the box and raise quickly from their lowest setting. You can extend them manually with the included side-wind handle or speed the process with a power drill, which is especially helpful for frequent use or when leveling multiple supports.

• Adjustable range from 16" up to 36" to match different RV clearances.
• Dual operation: drill-compatible spiral shaft plus side-wind handle for backup.
• Tether pins secure the jack position and prevent accidental retraction.
• Recommended to use on a level base such as wooden or concrete blocks for best stability.

What materials and design features make these jacks durable?

The supports are built from thick, heavy-duty steel and finished with a zinc powder coat to resist corrosion and abrasion from road use and outdoor storage. The hexagonal base shape increases footprint stability while the U-top cradles slide-out rails without requiring complex adapters.

• Zinc powder-coated steel for long-term rust resistance and toughness.
• Reinforced spiral shaft design reduces shaking under load and improves longevity.
• Solid tether pin system stops unintended movement during use or travel.
• Sold as a 2-pack so you can support both sides or use pairs where needed.

Will these supports fit my camper and when should I use them?

The 5.3" U-shaped top is shaped to fit the majority of aftermarket and factory slide-out frame rails. They're a practical choice whenever a slide-out shows any bend, sag, or you want to minimize wear over long stays—especially on uneven campsites or soft ground.

• Fits many common slide-out rail profiles due to the wide U-top design.
• Ideal for older trailers with known sag or new units where extra protection is wanted.
• Use on level, supported ground with pads or blocks for optimal performance.
• Includes 5-year after-sales support for product reliability.

Who is this for: SUNSHINE FARMRE RV Slide Out Supports are for RV owners, full-time travelers, and weekend campers who want to protect slide-out assemblies from sag and reduce interior sway. They suit owners of travel trailers, fifth-wheels and campers who need a heavy-duty, easy-to-use stabilizing solution that works with power tools or by hand and performs reliably in varied camping conditions.
