RVGUARD RV Stack Jacks 4-Pack Aluminium Stabilizer Jacks 11"–17" 6000 lb Each, Nestable Lightweight

RVGUARD RV Stack Jacks 4-Pack are compact aluminum stabilizer jacks designed to stop RV sway and steady low-clearance rigs, each stack supporting up to 6,000 lbs for stabilization (not for lifting).

These stack-style stabilizer jacks give owners of travel trailers, motorhomes and campers a lightweight, corrosion-resistant way to reduce bounce and unwanted movement at campsites. Made from cast aluminum with rubber pads and a square base, the four-pack nests for compact storage and extends from 11" to 17" to suit lower-to-the-ground setups. They’re intended only for stabilizing and leveling — not for lifting or vehicle support during maintenance.

How do these stabilizer jacks stop RV movement?

The RVGUARD stack jacks create additional contact points between your camper and the ground to reduce rocking when people move inside or wind hits the rig. When positioned under frame points and turned to the proper height, they firm up the chassis and limit side-to-side sway and vertical bounce.

• Four jacks provide multi-point stabilization around the rig.
• Rubber pads improve grip and protect surfaces from marring.
• Square base increases footprint to prevent sinking on softer ground.
• Recommended to use with wood or concrete blocks for extra support.

Will these work with my low-clearance trailer or RV?

Yes — the jacks extend from 11" to 17", which makes them well-suited for lower-to-the-ground trailers and RVs where taller stabilizers won’t fit. Their stackable design lets you compactly store them when not in use, and the lightweight aluminum is easier to handle than heavier steel alternatives.

• Minimum height: 11"; maximum height: 17" for tight-clearance rigs.
• Total kit weight under 40 lbs for easy lifting and placement.
• Cast aluminum construction resists rust and corrosion at campsites.
• Nestable design saves storage space in compartments or garages.

How do I use the T-handle jacks safely and correctly?

Place each jack under a recommended stabilizing point, then rotate the T-shaped handle to raise the inner tube until the jack contacts the ground and firms up the chassis. Do not attempt to lift the vehicle; these jacks are for stabilization only. For added security, place the jack on a level, solid surface or set it on treated wood/concrete blocks before final tightening.

• Position jacks at four corners or strategic chassis points for balance.
• Spin the T-handle to extend until the RV no longer bounces.
• Always use on a firm base or with blocking to prevent sinking.
• Never use these jacks to raise the RV for repairs—stabilization only.

What are the build and load characteristics of these jacks?

Each RVGUARD stack jack is constructed from cast aluminum to deliver a high strength-to-weight ratio while resisting rust and corrosion. The manufacturer specifies up to a 6,000 lb stabilization capacity per jack, making this set suitable for many trailers and campers when used as directed.

• Material: cast aluminum for durability and corrosion resistance.
• Load rating: up to 6,000 lbs per jack for stabilization purposes.
• Base design: square foot for improved ground contact and stability.
• Includes rubber pads to protect surfaces and improve grip.

Who is this for: RVGUARD RV Stack Jacks are intended for RV, trailer and camper owners who need a portable, corrosion-resistant stabilization solution for campsites, seasonal parking or storage. They work best for lower-clearance rigs and users seeking light, nestable equipment to reduce sway and improve interior comfort—but are not a substitute for service jacks or axle supports when performing repairs.
