RVGUARD RV Stack Jacks 4-Pack Aluminum Stabilizer Jacks 6000 lb ea, Nesting Compact 11–17"

When you want a quick, portable way to steady an RV or camper without using the vehicle's hydraulic system, these cast-aluminum stack jacks give a corrosion-resistant, lightweight option. They are designed for stabilization only — not for lifting a vehicle — and work best on lower-clearance rigs. Each jack nests for compact storage, and rubber pads help prevent slipping and protect surfaces.

How do these jacks improve campsite stability?

These stack jacks reduce sway and bounce by creating fixed contact points between the RV frame and the ground. They screw up to the desired height and lock in place, transferring movement away from living areas to the ground. Use them in pairs or all four corners to minimize rocking when people walk inside or wind hits the rig.

• Each jack supports up to 6000 lb, offering heavy-duty stabilization capacity.
• Rubber foot pads increase grip and protect surfaces from scratches.
• Square-base design resists tipping on firm ground.

Are these jacks easy to set up and store?

Yes — the threaded "T" handle operation lets you raise each jack quickly by hand without tools. When not in use the jacks nest together to save space in your storage compartment. They weigh under 40 lb for the 4-pack, so they’re manageable for one person to carry and position.

• Simple hand-crank operation via the "T" handle — no ratchet or hydraulic pump required.
• Compact nesting design fits small storage bays and garages.
• Lightweight cast-aluminum construction makes transport easier.

What are the size and material details I should know?

Each jack extends from approximately 11 inches to 17 inches, making them suited to lower-to-the-ground RVs and trailers. They are made from cast aluminum for corrosion resistance and reduced weight, though they are intended only for stabilization — never for lifting the vehicle. For added stability on soft ground, place a wood or concrete block beneath the base.

• Extension range: about 11" to 17" for low-clearance vehicles.
• Material: anti-rust cast aluminum for long-term outdoor use.
• Recommendation: use blocks beneath the base on soft or uneven ground.

How should I use these safely at the campsite?

Position a jack under each corner or at recommended support points, then turn the handle until the pad makes solid contact with the ground. Only use the jacks for stabilization while the RV is parked and the vehicle’s own jacks or leveling system should remain the primary lift if needed. Inspect the ground for firmness, and block or pad the base if necessary to prevent sinking.

• Place jacks only after the RV is parked and wheels chocked.
• Do not use to raise the RV — stabilization use only.
• Use supporting blocks for extra footing on soft surfaces.
