Gooseneck Couplers

Most gooseneck trailers are designed to be towed on a gooseneck hitch ball located in the bed of the tow vehicle. However, this king pin and pipe assembly is designed for those wanting to tow a gooseneck trailer with a 5th wheel hitch. The king pin is specially designed with zero bolster. The 4" O.D. round tube will fit as a n inner pipe on most standard gooseneck outer tubes. Always follow manufacturer's torque specs when tightening set screws.

HammerBlow has a fabricated cone shaped bottom plate. The #HBQ2516ADJ features a user-friendly cam lock height adjustment design allowing hands free modifications.

Can be mounted on the trailer as a standard gooseneck coupler or in the truck bed. Removable steel pin secures hitch ball in the cast housing. Meets rated capacity, only when used with the pin supplied.

The Standard Gooseneck Couplers, SH and BH series, feature a spring-action automatic closing bottom plate and deep cast cone-shaped bottom plate for easier line-up of coupler and ball. The BH series offers greater capacity, utilizing a forged steel one-piece top plate.
