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.
A worn or fussy coupler turns every hookup into a fight, and a rusty one can start chattering loose on the ball right when you are loaded and rolling. This medium duty Wallace coupler puts an end to both. It drops over a 2" hitch ball and auto-latches on its own, so you back the trailer down, the head locks the ball in place, and you are hooked. It bolts to trailer A-frames that run vertical channels, and it pairs with our Shocker Hitch air trailer tongue mounts. It carries up to 12,000 lbs of trailer with 1,200 lbs on the tongue, so there is real headroom when the load rides heavy up front. The full black powder coat shrugs off salt, road spray, and grime so it keeps latching clean season after season. Two 4-1/2" long by 5/8" diameter bolts and 2 lock nuts come in the box.

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