RVGUARD RV Stack Jacks 4-Pack — Cast Aluminum Stabilizer Jacks, 11–17" Height, 6,000 lb Support

RVGUARD RV Stack Jacks 4-Pack are compact, cast-aluminum stabilizer stands that provide solid, anti-corrosion support for low-clearance RVs and campers.

If you need a lightweight, rust-resistant way to steady your trailer or motorhome while parked, these stackable jacks offer an economical stabilization solution. Built from corrosion-resistant cast aluminum with a broad square base and rubber contact pads, each jack is rated to support up to 6,000 pounds for stabilization purposes (not for lifting). They nest together for storage and extend to give 11"–17" of support height, making them suitable for lower-to-the-ground rigs when used with proper blocking.

How do these jacks keep my RV steady?

The RVGUARD stack jacks create firm contact points beneath your chassis to minimize rocking and movement when parked. Their wide square bases spread load across soft or uneven surfaces, and the rubber pads reduce metal-to-surface wear.

• Cast-aluminum construction resists rust and reduces weight for easier handling.
• Square base design distributes weight to prevent sinking in soft ground.
• Rubber pads cushion contact and protect frame mounting points.
• Each unit stabilizes up to 6,000 lbs for stationary support (not for lifting).

Will these jacks fit my RV and how high do they reach?

These stack jacks extend from approximately 11 inches to 17 inches, so they’re best for rigs with lower ground clearance or as supplementary stabilizers. Because they’re intended for stabilization only, they work well paired with wood or concrete blocks to achieve the best height and secure bearing surface.

• 11" minimum to 17" maximum extension for low-to-medium clearance vehicles.
• Recommended for use with blocking to improve height and stability.
• Not designed as a lifting jack — use only for stationary stabilization.

How simple are they to set up and store?

Setup is straightforward: slide each jack under the frame, turn the T-handle to engage the stacking sections until you reach the desired height, and position a pad or block under the base as needed. When finished, the components nest together so you can store all four in a compact space in your storage bay.

• T-shaped handle for hand-operated adjustment without special tools.
• Nested design reduces storage footprint in RV compartments.
• Total kit weight under 40 lbs, making transport and placement easier.

What materials and limits should I be aware of?

The jacks are made of durable cast aluminum to resist corrosion and keep overall weight low. Each stand is rated to support up to 6,000 lbs for stabilization, but they are explicitly not intended for lifting or serving as a primary support during repair work.

• Cast-aluminum body: corrosion-resistant and lightweight.
• 6000 lb per-unit stabilization rating — for stationary support only.
• Use with wood or concrete blocks to improve load distribution when necessary.

Who is this for? These RVGUARD stack jacks suit RV owners, weekend campers, and trailer operators who want a portable, rust-resistant way to reduce bounce and sway while parked. They’re especially useful for lower-clearance campers and those who prefer a compact storage solution. If you need to raise an axle or perform underbody repairs, choose a dedicated lifting jack — but if your goal is safe, easy stabilization at campsites and parking spots, this 4-pack provides a practical option.
