Adapter to Fit Curt 5th Wheel Hitch to 2019 GMC Sierra 2500 OEM Pucks

Question:

I have a 2019 GMC Sierra 2500. It has the factory gooseneck. I have a curt fifth wheel hitch but assume I need the gooseneck to fifth wheel bracket. Maybe you all can suggest something for me. Thanks

Hey Bryan, if you have the factory gooseneck hitch in your 2019 GMC Sierra 2500 that would indicate you have the factory underbed rail kit for fifth wheel hitches too as the two rail kits are the same thing. So since you have a Curt fifth wheel hitch currently that is designed to fit above bed rails what you'd want is the Curt rail kit adapter part # C47BR which fits the OEM pucks you have and provides the type of rails your Curt hitch needs.
