Save space and stay organized with CURT HD wheel chocks. These unique wheel chocks mount to the trailer frame and prevent the need to store them inside your truck or RV. The unique bracket mounts to the trailer frame and includes snap-rings which allow you to quickly attach and detach the chocks outside of your vehicle. No more dirty wheel chocks inside your truck or SUV! Made from heavy-duty materials, the dense rubber construction provides improved traction, preventing chock slippage or movement. The high-density steel bracket is built to last and avoids bending or breaking with use. Finished with a weather resistant liquid A-coat that prevents rust and corrosion and a bold orange powder-coat finish. This kit includes self-tapping screws for attaching the bracket to the trailer frame, and a wire lanyard that prevents loss of the snap-ring clips when not in use.

The CURT 22803 is a wheel chock system for trailers that prevents wheel movement when parked. It includes a mounting bracket, wheel chock, self-tapping screws, carriage bolts, washers, nylock nuts, and clamp brackets. The system can be installed using either a drill-based method or a clamp-on method without drilling.
The manual does not specify which trailer models or types are compatible with the CURT 22803. Before purchasing, contact CURT Product Support at 877.287.8634 or visit curtmfg.com to confirm fitment for your specific trailer.
For drill installation: socket set, drill, ratchet, 11/32" drill bit, torque wrench, paint marker, and box-end wrench set. For clamp-on installation: socket set, ratchet, torque wrench, and box-end wrench set (drill not required).
The kit includes: 1 mounting bracket, 1 wheel chock, 4 self-tapping screws (3/8"-16 x 1"), 2 carriage bolts (3/8"-16 x 1"), 2 carriage bolts (3/8"-16 x 5"), 2 flat washers (3/8"), 4 nylock nuts (3/8"-16), and 2 clamp brackets.
Yes. Before drilling, you must consult your trailer manufacturer to ensure your desired location is safe and will not affect the trailer's capacity. This is required regardless of which installation method you choose.
Always check for wiring, plumbing, brake lines, or any other obstructions inside and outside the mounting location prior to drilling or clamping. Some obstructions may be hidden inside the frame. Failure to check may result in damage to critical trailer systems.
No. The CURT 22803 offers two installation methods: drill installation (which requires drilling 11/32" pilot holes) and clamp-on installation (which requires no drilling). Choose the method that suits your trailer and preference.
An 11/32" drill bit is required. Use the mounting bracket as a template to mark the pilot hole locations before drilling.
1. Choose the desired location and orientation of the mounting bracket on the trailer. 2. Using the mounting bracket as a template, mark and drill 11/32" pilot holes. 3. Secure the mounting bracket with the provided 3/8" self-tapping screws and torque to 10 ft-lbs. 4. Remove the lynch pin to allow the wheel chock to be installed on each support arm. 5. Re-install the lynch pins to secure the chocks on the support arms.
1. Choose the desired location and orientation of the wheel chocks with adequate clearance to install the clamp brackets in front and behind the frame. 2. Loosely secure the mounting bracket to the outside clamp bracket with two short carriage bolts and two nylock nuts; rotate to desired orientation and torque to 10 ft-lbs. 3. Position the assembly in your desired location and secure by installing two long carriage bolts above and below the frame through the second clamp bracket, then secure with two flat washers and nylock nuts torqued to 10 ft-lbs. 4. Remove the lynch pin to allow the wheel chock to be installed on each support arm. 5. Re-install the lynch pins to secure the chocks on the support arms.
The 3/8" self-tapping screws must be torqued to 10 ft-lbs.
All carriage bolts and nylock nuts (both short and long bolts) must be torqued to 10 ft-lbs.
Wheel chocks must be installed flush and centered on the tires to function effectively. On a level grade, chocks should be used in the front and rear of the tires. On a downhill grade, chocks should be applied on the downhill side of the tires. Wheel chocks should always be used in pairs; multiple pairs may be required in extreme situations.
Always ensure the parking brake is applied and functioning prior to installing wheel chocks. Do not use wheel chocks if there are any visual signs of damage, as damaged chocks may not work effectively and could result in property damage, serious injury, or death.
Periodic inspection of the product should be performed to ensure all hardware and components remain secure. The manual does not specify an inspection interval; consult the manufacturer for recommended maintenance schedules.
The manual does not list specific trailer models. Contact CURT Product Support at 877.287.8634 or visit curtmfg.com to confirm fitment.
