So if you have the other guy´s industry standard rails, just take out your old hitch and replace it with an American made hitch from Pullrite and just drive. Or if your starting from scratch, you can install Pullrite´s better than theirs industry standard base rails and brackets. All Super 5th hitches feature PullRite's unique gear driven rotary latch, with automatic locking mechanism, for a safer, tighter connection between the truck and trailer. All Super 5th also have a full double pivot, fully articulating head. The rotary latch wraps 140° around the king pin, reducing wear, and minimizing "bump", allowing only .030" tolerance between king pin and latch. Our new line of industry standard hitches simply pin to existing base rails in your truck--eliminating the need to reinstall and drill additional holes!
