AUH X-Shape Wheel Chock Stabilizer for RV Tandem Tires — Galvanized Adjustable Steel, Fits 3.9–12.6 in

The AUH X-Shape Wheel Chocks Stabilizer is a heavy-gauge, adjustable steel support that locks between tandem RV tires to steady travel trailers, motorhomes, and fifth-wheels when parked.

When you park a travel trailer or motorhome, lateral and fore-aft movement from wind, loading, or uneven ground can make living aboard uncomfortable. The AUH X-Shape stabilizer installs between dual wheels to create a rigid bridge that reduces sway and axle movement. Built from galvanized steel and designed to fit a wide range of tandem wheel spacings, this stabilizer is intended to add a durable, easy-to-adjust layer of support without permanent modification to your RV.

How does this stabilizer reduce trailer movement?

The X-shape forms a secure connection between two adjacent wheels, using the vehicle’s own weight to lock the unit in place. With the stabilizer bridging the tires, axle twist and side-to-side rocking are significantly reduced, improving interior comfort and appliance stability.

• Steel construction creates a rigid support spanning both tires.
• Raised tread on the footplate increases grip against the tire sidewall.
• Galvanized finish maintains integrity in outdoor conditions.

What sizes and vehicles will this fit?

AUH designed the chock to be adjustable so it works with many RV tandem setups. The unit’s extension range accommodates wheel spacings common to travel trailers, fifth-wheels, toy haulers, and Class A motorhomes, making it versatile for most trailers with dual wheels.

• Adjustable span: fits wheelbases approximately 3.9 in to 12.6 in.
• Suitable for travel trailers, fifth-wheel trailers, toy haulers, and Class A motorhomes.
• Works with common tandem wheel arrangements without wheel removal.

How easy is installation and adjustment?

Installation can be completed quickly using the included drill bit for faster anchoring or with a standard wrench for manual adjustment. The product supports two installation methods so you can choose the faster drill-assisted option or the straightforward wrench-tightening approach depending on tools and preference.

• Includes a drill bit for rapid installation in seconds.
• Wrench-adjustable alternative for tool-only setup.
• No permanent modification required to tires or axles.

How does the finish and design stand up to outdoor use?

The stabilizer’s galvanized coating resists rust and corrosion from exposure to rain, sun, and seasonal conditions, extending service life. Additionally, the raised tread design on contact surfaces enhances traction and helps prevent slippage against the tire sidewall.

• Galvanized surface prevents rust in wet environments.
• Raised footplate tread improves tire grip for secure placement.
• Heavy-gauge steel construction for long-term durability.

Who is this for: The AUH X-Shape Wheel Chocks Stabilizer is aimed at RV owners, full-time or seasonal travelers, and anyone who parks trailers or motorhomes frequently and wants a non-invasive way to cut sway and axle movement. It’s ideal if you need a robust, portable stabilizer that fits a broad range of tandem wheel spacings and can be installed with basic tools.
