Towmax Camper Wheel Chock Stabilizer — X-Shaped Tandem-Axle RV Chocks, 3.5"–12" Fit with Ratchet Kit

Towmax Camper Wheel Chock Stabilizer is an X-shaped, heavy-duty tandem-axle stabilizer kit that fits 3.5"–12" wheel gaps to reduce trailer rocking and keep your RV steady while parked.

When you park a travel trailer or camper with tandem wheels, small movements from walking inside or wind can make the rig feel unstable. The Towmax X-shaped wheel chock stabilizers are engineered to press between paired tires and apply opposing force, limiting sway and movement without permanent installation. The kit arrives ready-to-use with two stabilizers, a ratchet wrench, socket adapter, gloves and a storage bag so you can set up and stow away quickly.

How does this X-shaped stabilizer reduce trailer movement?

The scissor-style X frame works by expanding between tandem tires so opposing pressure locks the wheels relative to each other. That opposing force reduces lateral and fore-and-aft movement, making the trailer feel firmer underfoot. Because it wedges between tires rather than bolting to the chassis, it’s removable and won’t alter the vehicle.

• Applies equal pressure across paired tires to minimize rocking.
• Scissor action tightens to fit gaps from 3.5" to 12" without drilling.
• Use one stabilizer per side of the axle for balanced support.

What materials and construction make it durable?

Each chock is built from heavy-duty steel with reinforced joints and a protective coating to resist outdoor wear. The rigid X-frame design spreads clamping force evenly so the metal holds shape under load. Welds and connectors are designed to avoid bending when tightened to secure the gap between tires.

• Heavy-gauge steel X-frame for strength and rigidity.
• Reinforced connection points to withstand repeated use.
• Protective finish resists scratches and exposure to elements.

How do I install and remove the Towmax wheel chocks?

Installation is straightforward: measure the gap between tandem tires, expand the X chock to that width, slide it into the gap, and tighten until snug. The kit includes a ratchet wrench and socket adapter for manual or powered tightening—no drilling or permanent parts are needed. Gloves are included for hand protection during setup and removal, and the chocks collapse for compact storage.

• Measure wheel gap (3.5"–12") before expanding chock.
• Tighten with the included ratchet, socket adapter, or drill.
• Pack tools and chocks into the supplied storage bag when finished.

Will these stabilizers fit my trailer’s tires and routine use?

The Towmax kit is made for tandem-axle configurations where tires sit close enough to accept an X chock. It fits most common tandem gaps between 3.5" and 12" and is intended for parked stabilization rather than towing. Regularly inspect the frame and hardware for wear before each season, and follow safe lifting and blocking practices when working around tires.

• Compatible with many tandem-axle travel trailers, campers, and light RVs.
• Designed for stationary stabilization while parked, not for towing.
• Simple visual checks help keep the stabilizers performing reliably.

Who is this for: The Towmax Camper Wheel Chock Stabilizer kit is ideal for RV owners, camper and trailer users who want an easy, removable way to steady tandem-axle rigs while parked. It suits weekend campers, seasonal travelers, and anyone who prefers a non-permanent stabilizing solution that stores compactly and sets up quickly.
