BAL X-Chock Wheel Stabilizer Pair — One-Handle, Adjustable 1-3/8"–10", Zinc-Plated Steel

The BAL X-Chock Wheel Stabilizer pair locks between tandem tires to stop tire shift and steady trailers, and it includes a hand ratchet for easy adjustment.

Designed as a slimmer follow-up to BAL's Deluxe Tire Locking Chock, the X-Chock squeezes into tighter axle spaces while exerting opposing force on two tires to hold them in place. Built from zinc-plated steel in the USA, this kit comes with two adjustable chocks and a plated 3/4" ratchet wrench so you can extend or retract the units quickly. The low-profile range and lockable feature make it useful for travel trailers, fifth-wheels, and many RV tandem-axle setups.

How does the X-Chock prevent tire movement during travel or storage?

The X-Chock works by pressing outward against both tires in a tandem pair, creating balanced pressure that resists shifting and sway. Once expanded to the correct width, the drive nut holds the chocks in place until you retract them with the included ratchet.

• Applies opposing force to both tires for stability
• Adjustable from 1-3/8" to 10" to match many axle gaps
• Ratchet-operated drive nut provides controlled extension and retraction
• Optional padlock can secure the chocks when stored or parked

What materials and construction make it durable outdoors?

Each X-Chock is made from zinc-coated steel to resist corrosion encountered on roads and in storage lots. U.S. manufacturing and robust plating extend service life, while the simple mechanical design minimizes maintenance points.

• Made in the USA from rust-resistant, zinc-plated steel
• Sturdy ratchet hardware resists bending under load
• Simple moving parts for easy, long-lasting use
• Limited lifetime warranty on mechanical components

How do you install and remove the X-Chock safely?

Installation takes only a few minutes: position a chock set between the tandem tires, use the included 3/4" ratchet wrench to extend until snug, and check alignment. To remove, retract with the ratchet and pull the chocks clear. No special tools or permanent mounts are required.

• Place chocks in the tire gap, centered between tires
• Turn the included ratchet wrench until chocks press firmly against both tires
• Retract with the wrench before moving the vehicle
• Padlock option available for extra security when parked

How adjustable is it for different tire and axle setups?

The X-Chock accommodates narrow to wide tandem gaps with a working range from 1-3/8" up to 10". Its slim profile helps fit axles where bulkier chocks won't, making it versatile across many trailer and RV layouts.

• Works with most travel trailers, fifth-wheels, and twin-axle RVs
• Slim design fits tight axle spacing not suitable for larger chocks
• Pairs with BAL 28015 padlock for theft deterrence
• Includes two chocks and a comfort-grip ratchet wrench for quick setup

Who is this for? The BAL X-Chock Model 28012 suits RV owners, tow vehicle operators, and fleet managers who need a compact, dependable way to prevent tire shift on tandem axles. It’s especially helpful when axle gaps are too narrow for bulkier chock designs, when corrosion-resistant construction matters, and when a fast, tool-assisted install/removal is preferred. If you tow frequently, park trailers for extended periods, or want a lockable stabilizer that’s simple to use, the X-Chock pair is built for those needs.
