CURT 5th wheel base rails are universal, meaning they can be used with any 5th wheel trailer hitch and in virtually any truck bed able to accept a 5th wheel hitch. They are compatible with all CURT and competitive 5th wheel trailer hitches and 5th wheel rollers, and their universal design also allows them to accommodate gooseneck adapters and Spyder gooseneck hitches.
