Pafessa RV Stabilizer Wheel Chock XL — 3.5" Static / 17" Travel Heavy-Duty Locking X-Chock 2-Pack

Pafessa RV Stabilizer Wheel Chocks are heavy-duty X-style scissor stabilizers that lock between tandem trailer tires to stop rocking and deter theft.

These Pafessa XL wheel chocks pair an X-shaped scissor design with robust zinc-coated steel, a locking cap, and included padlocks to create a dependable stabilizing system for travel trailers and tandem-axle campers. They adjust to span up to 17 inches of travel and sit at a static height of 3.5 inches, giving your trailer a steady anchor without touching suspension components. Built for frequent use, the units arrive prelubed and resist corrosion for long service life.

How do these X-chocks reduce trailer movement?

The Pafessa X-style stabilizers fit snugly between opposing tires and generate counterforce when tightened, which prevents forward-back rocking and side-to-side sway. Their louvered feet grip rubber without gouging, and the scissor geometry spreads load across both tires for greater stability than single-point chocks.

• Works between tandem axle tires to oppose motion on both sides
• Louvered feet hold tire surface securely without damage
• Scissor action transfers forces across two contact points
• Static height 3.5" and travel up to 17" to suit many tire setups

Are these chocks easy to install and adjust?

Yes — each unit includes a user-friendly handle and a ratcheting box-end wrench so you can position and tighten the X-chock quickly by hand. The threaded rod is prelubed for smooth operation, and pivot rivets are heavy-duty for repeated use, making setup fast at campgrounds or storage lots.

• Handle for simple mounting and removal between tires
• Ratchet box-end wrench included for accurate tightening
• Prelubed threaded rod ensures smooth adjustment
• Zinc finish and robust rivets reduce maintenance needs

How does the security/anti-theft feature work?

Pafessa stabilizers include a locking cap and a padlock with key to secure the scissor in its tightened position, preventing opportunistic theft of the chock and discouraging trailer tampering. Locking the mechanism keeps the unit from being loosened or removed without the key.

• Locking cap covers adjustment hardware to block tampering
• Padlock and key supplied for immediate security
• Steel construction resists forced removal attempts
• Helps protect both chock and trailer while parked

What materials and maintenance should I expect?

Pafessa X-chocks are made from high-grade steel with a zinc-coated finish and heavy-duty rivets at pivot points to resist corrosion and wear. Regular rinsing to remove road salt and occasional lubrication of the threads will keep the mechanism functioning smoothly for seasons of use.

• Zinc-coated steel frame for rust resistance
• Heavy-duty rivets at pivot points for durability
• Prelubed rod; reapply lubricant periodically
• Wipe or rinse after exposure to salt or heavy dirt

Who is this for: Pafessa XL X-Chocks are designed for travel trailer owners, RV renters, and fleet operators with tandem axles who want a durable, easy-to-use stabilizing solution that also adds theft deterrence. They are ideal if you need a compact, portable stabilizer that fits 3.5" static height setups and accommodates up to 17" of travel—especially useful at campsites, storage yards, or when loading and unloading where trailer movement matters.
