This setup turns every haul into a smoother trip. The Shocker 5th Wheel to Gooseneck Pinbox uses an air bag and cushioned bumpers to absorb road shock and cut down on chucking and jerking. The air system works in a forward-and-back motion to take out the lurch you feel when towing, giving you better control and a more comfortable ride. You can fine-tune the air pressure to match your trailer’s load so the ride feels just right whether it’s light or heavy.
Free up your truck bed by towing with your gooseneck hitch instead of a fifth-wheel plate. This adapter replaces the existing pin box and connects right to a 2-5/16" ball. Once installed, you get a clean bed when you’re not towing plus the flexibility to use one system for both work and travel.
Power and reliability are baked in. The heavy-duty steel tubing and 4140 cast steel socket give this coupler real strength for serious towing. It’s rated for 24,000 lbs gross towing weight and 6,000 lbs vertical load limit, so it’s ready to handle large fifth-wheel trailers and stay solid under pressure.
Hooking up shouldn’t be a chore. The simple lever lets you engage or disengage the locking mechanism without hassle, and the dual locking bars hold the ball in place to reduce rattle and add security. Grease zerk fittings at the pivot point make it easy to keep things moving smoothly over time.
The tough build is finished with a shot-blasted and powder-coated surface that stands up to rust and wear. It’s made to last through years of towing and rough roads, with a design that’s easy to maintain so you can spend more time towing and less time wrenching.
Note: Safety chain adapters are needed to attach the mandatory safety chains for your rig. Use SHK35MR (sold separately) for best results.

Totally satisfied. This hitch makes my 41ft toy hauler ride as smooth as if it weren’t there. I had to add 30psi to the air adjust. Perfect! A bit more of an alignment challenge on tow hookup, but practice makes it a smooth operation. Installation was a breeze with just one person. 5 stars!
