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.
When a trailer coupler gets old and sloppy, you feel it every time the ball works loose in the socket: a rattle at the hookup and extra slop that pounds on the tongue over frost heaves and hard stops. This heavy-duty Wallace coupler puts a solid, tight connection back on the front of your trailer. It is a forged coupler rated to 25,000 lbs tow and 2,500 lbs tongue weight, built for trailer A-frames with vertical channels and for our air trailer tongue mounts. It fits a 2-5/16″ hitch ball only. Hooking up stays dead simple: drop the coupler over the ball with the lever open, then pull the side lever to lock it down. The full black powder-coat finish holds off road salt and grime, so it keeps gripping season after season.

When to Order Just a Coupler
Already running a Shocker tongue mount and the original coupler is worn or damaged? A standalone Wallace or Demco coupler swaps out just the head, so you save money instead of replacing the whole tongue mount.
