PopUp 5th Wheel to Gooseneck Adapter | 2-5/16" Ball | KP2BP

Lock this adapter's 2" kingpin into a fifth-wheel hitch and you have a 2-5/16" gooseneck ball for a short move — no hitch swap. The solid kingpin sits on a 1/2" thick, 10" diameter bolster plate; the ball and pin are rated 30,000 lb and the whole unit is plated. It works on pickup and semi/tractor fifth wheels alike, but PopUp is clear that it's for short tows: the fifth wheel should be blocked against tilting and it's not meant for regular highway use.

⚠️ Not for regular highway use — short-distance moves only. For a permanent setup see the PopUp flip-over gooseneck hitch.
