A 5th Wheel King Pin aren't often purchased on their own as they typically come with the 5th wheel trailer you purchased. Our selection of king pins have their purpose however, we offer a number of options that will allow you to replace your current 5th wheel king pin or extend a king pin.

A 5th wheel king  pin is a round steel shaft attached to the fifth wheel trailer's coupler, this king pin slides into the jaws of the 5th wheel hitch on the truck for a secure mount.

Most 5th wheel trailers come with the king pin already mounted to the trailer so they're not typically necessary unless you're looking to replace or upgrade your current setup, or have made some changes and need the right king pin or king pin adapter to tow.

If you're considering the replacement of a king pin, you may want to look at buying a complete 5th wheel coupler that will come with the king pin already included.

Refer to our post on What Are 5th Wheel Couplers to see what options are out there to perhaps improve your 5th wheel towing system.
