Stop destroying your trailer and cargo.

Every bump, pothole, and expansion joint sends a violent jolt through your trailer frame, damaging cargo and wearing out your truck. Shocker Air Ride Hitches absorb that punishment at the coupling, before it reaches your trailer.

The Wallace Auto-Locking Trailer Coupler Kit provides a medium-duty towing solution for A-frame trailers, centered around a precision-engineered 2" hitch ball connection. This professional-grade coupler is rated for a 12,000lbs gross trailer weight and features an integrated quick-latch mechanism that automatically snaps into place when lowered onto the ball. Designed for ease of use and long-term reliability, the unit is finished with a heavy-duty powder coat to resist rust and corrosion, while a simple release handle ensures an effortless disconnect even after heavy hauling. Providing the structural backbone for this kit is a 12" tall, 6-hole vertical channel designed to be welded directly to the trailer tongue. While the coupler is rated for 12,000 lbs, this reinforced 5-position vertical channel is engineered to handle up to 20,000 lbs, offering a massive margin of structural safety and rigidity. This over-built design allows you to bolt the coupler at various heights to ensure a perfectly level tow, providing the heavy-duty foundation needed for the towing vehicles and demanding environments. Professional welding required to install the 6 hole, 5 position vertical channel onto your trailer tongue. California Residents: Prop 65 Warning
