VEVOR RV Slide Out Support Jacks 2-Pack, 20-48 in Adjustable Stabilizers — 5,000 lb Capacity Each, Heavy-Duty

VEVOR RV Slide Out Support Jacks are a 2-pack of heavy-duty, adjustable stabilizers that prevent sagging and movement of RV slide-outs, each rated to support up to 5,000 lbs.

If your camper or travel trailer has a slide-out that wobbles, sags, or creaks when extended, these slide out support jacks provide a simple mechanical fix. Built from thick Q235A steel with protective coatings and galvanised screw handles, the pair is engineered to add rigidity and steadiness at the corner or midpoint of most slide-outs. They fold compactly for storage and adjust to a wide height range, making them a practical accessory for seasonal camping, long stays, or whenever your slide-out needs extra reinforcement.

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

The VEVOR slide out stabilizers transfer load from the thin slide-out frame down to the ground, reducing flex and side-to-side play. When set up under the slide-out support bars, they lock into position with a screw-handle lift for a snug, vibration-resistant fit.

• Each jack supports up to 5,000 lbs for concentrated load control.
• 0.08"/2mm thick steel tubing prevents bending under pressure.
• Galvanized screw handle lets you fine-tune tension and height.

Will these fit my RV — what are the adjustment and size limits?

These stabilizers extend from 20" to 48", covering most camper and travel trailer slide-out clearances. Their compact folded measurements and lightweight design make them suitable for storage in typical RV compartments.

• Adjustable range: 20"–48" (500–1230 mm) to match different ground clearances.
• Individual jack dimensions: 20.1 x 5.3 x 5.3" and 8.52 lbs for easy handling.
• Sold as a 2-pack — total weight ~17 lbs for transportability.

How easy is setup and what tools or accessories are recommended?

Setup is manual and tool-light: unfold the jack, place the bracket under the slide-out support bar, then use the folding handle to raise and lock the jack against the bar. On soft or uneven ground, use wooden or concrete leveling blocks under the foot to improve stability.

• Folding handle operation for controlled lifting without power tools.
• Use 2x4 or dedicated leveling blocks on grass or dirt for firm footing.
• Compact size allows one person to position and adjust each jack.

What materials and finishes ensure longevity outdoors?

The jacks are made from Q235A steel with a spray-plastic protective finish and galvanized screw-handles to resist abrasion and corrosion. Those finishes reduce surface rust and keep moving parts functional for seasons of use.

• Q235A structural steel construction for strength and durability.
• Spray-plastic coating to resist the elements and scratches.
• Galvanized 20# steel handles for wear resistance during adjustment.

Who is this for? These VEVOR slide out support jacks suit RV owners, full-time travelers, and seasonal campers who want a reliable, portable way to eliminate slide-out sag, reduce noise, and protect slide mechanisms. They work well for single-operator setups, owners of travel trailers and motorhomes with standard slide-out support bars, and anyone who prefers mechanical, maintenance-friendly reinforcement over permanent modifications. Note: always follow manufacturer safety guidelines for load distribution and placement; use blocking on soft ground.
