Sulythw RV Wheel Stabilizer Chocks X-Shaped — 2-Pack Adjustable Steel, Fits 3–11.5 in Tyres

Sulythw X-Shaped RV Wheel Stabilizer Chocks are adjustable, heavy-duty wheel stabilizers designed to lock tandem tires together and reduce front-to-back rocking for trailers, RVs, and trucks.

These X-shaped stabilizer chocks use a multi-fulcrum design and steel construction to brace two adjacent wheels, stopping rocking and improving steadiness on uneven ground. They retract to 3" and expand to 11.5", fitting many tandem-wheel setups. The kit includes a quick wrench, nut driver, and a drill adapter so you can tighten by hand or speed-install with an electric drill (drill not included).

How do these stabilizers stop my trailer from rocking?

The Sulythw X-shaped design applies counterforce between two tires, preventing front-to-back movement by locking the wheels together. Its adjustable pedal feet match the tire curve and the raised ribbed surface increases grip, reducing slip without damaging rubber.

• Multi-fulcrum X structure distributes pressure evenly across both tires.
• Raised ribbed pedal increases friction to prevent sliding.
• Thickened steel body resists bending under load.
• Protective paint resists corrosion for outdoor use.

Will these fit my RV, trailer, or truck tires?

The stabilizers extend and retract to accommodate a range of tire spacing: minimum 3" retracted to a maximum 11.5" extended. They’re intended for tandem and dual-wheel setups common on travel trailers, fifth-wheels, toy haulers and heavy-duty trucks—measure the gap between tires before ordering.

• Minimum closed width: 3"; maximum open width: 11.5".
• Suitable for tandem-wheel campers, motorhomes, and heavy trucks.
• Adjustable pedal conforms to different tire profiles.
• Compact enough to store in typical RV compartments.

How do I install and adjust the X-shaped wheel chock?

Installation can be done by hand with the included quick wrench and nut driver or quickly with an electric drill using the supplied drill adapter. Place the chock between tires, expand until snug, then tighten; the drill adapter lets you secure the unit in seconds for a less fatiguing setup.

• Hand tools included: quick wrench and nut driver.
• Drill adapter included for fast powered tightening (drill not included).
• Turn the wrench to expand or retract for a precise fit.
• Designed for easy removal when ready to travel.

Will these chocks damage my tires or corrode outdoors?

Sulythw designed the pedals with a raised ribbed contact surface to increase traction while minimizing concentrated pressure points that can harm tire sidewalls. The heavy-gauge steel is coated with a protective paint layer to resist rust and corrosion after exposure to sun, rain or snow.

• Ribbed pedal design prevents slippage while protecting tire rubber.
• Thickened steel construction for long-term strength and durability.
• Protective paint finish reduces rust from outdoor elements.
• Suitable for repeated seasonal use without significant wear.

Who is this for: The Sulythw X-Shaped RV Wheel Stabilizer Chocks are made for RV owners, trailer haulers, and fleet operators who want a compact, durable way to stop rocking and improve stability when parked. Ideal for campers who set up on uneven or soft ground, owners of tandem-wheel trailers, and anyone who prefers a reusable mechanical stabilizer that installs quickly with a wrench or power drill.
