RVGUARD RV Stack Jacks Stabilizer Stands 4-Pack — 11"–17" Aluminum, 6,000 lb Capacity Each

RVGUARD RV Stack Jacks 4 Pack are lightweight aluminum stabilizer stands that prevent RV sway and provide up to 6,000 lbs support per jack for improved campsite stability.

These RVGUARD stack jacks are purpose-built stabilization aids for trailers, campers, and motorhomes that need reliable, portable support while parked. Made from corrosion-resistant cast aluminum with a square base and rubber pads, the set of four stacks nests together for compact storage and extends from 11" to 17" to suit lower-clearance rigs. Note: these jacks are designed strictly for stabilization and leveling, not for lifting the vehicle.

How do these stack jacks improve campsite stability?

The stack jacks distribute weight and reduce bounce, sway, and movement when people walk inside or when wind hits your RV. Each jack's wide square base and rubber pad increase surface contact to resist sinking on softer ground. They are intended to be placed at the RV's corners or under frame points to create a firmer footprint while parked.

• Each jack is rated for 6,000 lbs of stabilization capacity.
• Square base design resists tilting and sinking on packed or leveled sites.
• Rubber pad minimizes slipping and protects RV frame contact points.

Can I adjust the height to level my RV?

Yes — each RVGUARD stack jack extends from 11" to 17", letting you fine-tune leveling for low-to-medium-clearance rigs. Height is adjusted by turning the included T-handle to stack or unstack segments until you reach the desired height. For safety and stability, always place jacks on firm surfaces or use wood/concrete blocks under the base for better support.

• 11"–17" extension range fits lower-to-the-ground trailers and campers.
• Simple T-handle twist operation for precise incremental adjustments.
• Recommended use with support blocks for maximum surface stability.

Are these jacks durable and weather-resistant?

Constructed from cast aluminum, the RVGUARD stack jacks resist rust and corrosion far better than plain steel alternatives, keeping them lightweight while maintaining structural strength. The metal finish and sturdy build are intended for repeated seasonal use; however, routine inspection and proper storage will extend service life. When nested together they’re easy to transport and less prone to damage in storage.

• Cast aluminum construction for rust resistance and low weight.
• Rubber pads protect contact surfaces and add grip in wet conditions.
• Compact nesting design simplifies storage and protects parts.

How do I use these jacks safely with my RV?

Position a jack beneath a recommended stabilization point on your RV frame, then twist the T-handle to stack up segments until the rubber pad firmly contacts the RV. Do not use these jacks to lift the RV off its tires; they are for stabilization only. For best results, set each jack on level, solid ground or use blocking beneath the base to prevent sinking or shifting.

• Place under factory-recommended stabilizing points or frame crossmembers.
• Use wood or concrete blocks under the base on soft or uneven ground.
• Never use the jacks to raise the RV for wheel removal—stabilization only.

Who is this for: RVGUARD RV Stack Jacks 4 Pack suit RV owners, weekend campers, and full-time travelers who want a lightweight, corrosion-resistant stabilization solution for low-clearance rigs. If you need compact, easy-to-store stands that reduce interior bounce and exterior sway while parked—without the weight and corrosion concerns of steel jacks—this 4-pack is designed to meet those needs. Remember these are stabilizers, not lifting devices; pair them with proper blocking and follow safe setup practices.
