PopUp Flip-Over Gooseneck Hitch for Semi-Tractors | 30K & 45K

A gooseneck hitch for trucks that already carry a fifth wheel. PopUp's flip-over unit bolts behind the fifth wheel on a standard 34" semi-tractor or cab & chassis frame (three 3/4" bolts per side; needs 10" on top of the frame and 4" down each side) and is fabricated from 1/2" steel. The ball rotates in its machined socket — it doesn't grind against the coupler, and a spring-loaded stainless pin lets you pull it and store it inverted for a flat floor and full fifth-wheel access.
