The Pop Up Towing 45K Flip-Over Gooseneck Hitch for Semi, Cab, and Chassis Trucks installs behind the fifth-wheel on standard 34″ frames.
NOTE: PopUp Towing Products Semi-Hitches will NOT fit truck frames with an outside width greater than 34″. The 34″ frame width is an industry standard for most semi-tractors as well as cab and chassis pickup trucks. As always measure your frame width precisely before ordering your semi-hitch.
Because the Flip-Over Ball rotates in its socket, hitch ball and coupler life are greatly extended. They don’t “grind” against each other when you tow. The other advantage of a rotating ball is that it stays “free” in its socket so you can easily turn it over when you want a level floor in your truck.
The ball is locked in the one-piece machined steel socket with a spring loaded stainless steel pin. Simply rotate the handle to retract the pin, pull the ball out and store it inverted and out of the way in the socket giving full access to the fifth-wheel.
