Wallace Forge Kingpin to Gooseneck Ball Adapter - Made in U.S.A.;

This fifth wheel to gooseneck adapter allows your gooseneck trailer to be towed by a fifth wheel hitch. The adapter has a solid 2" forged kingpin with a 1/2" bolster. The hardened steel 2-5/16 inch ball is machined to the kingpin and is rated for 30,000 lbs. Product is unpainted so some surface rust may be present when received.
