My pickup engine went down being unable to pull a my gooseneck with a ball application I ordered your 4 in kinpin adapter for a gooseneck trailer as you can see in the pictures it pinned in perfectly with no trouble at all with your adapter im able to get my trailers moves while repairs are made and with it i'll just have to use the fifth wheel hitch for the pickup witch is much more easy to use than a goose ball 313920

Quality manufacturing. I have a 1989 gooseneck car hauler with a 4 1/2 inch OD square tube and I'm changing it over to a king pin. This is a 4 inch OD and it fits perfectly inside my existing tubing. The holes aren't the same size as my original 4 1/2 inch but that's an easy fix. I can't wait to be able to tow my 5th wheel and my car hauler without having to switch from king pin to gooseneck ?????? 299577
