12" Gooseneck Adapter

Answer the Question

You will need to measure from the top of the gooseneck ball installed, or from the bed if the truck if the ball is not installed, to the bottom of the pin box on your 5th wheel. Then you can subject 3" from the measured distance to account for the adapter settling on the ball. The result will provide the adapter length needed. Keep in mind, when doing all the measuring that the truck and 5th wheel be as level as possible. Additionally, clearance of the pinbox will need to be checked to ensure full turns are still possible.
