CURT hitch adapters can be used for many different purposes when hitching up a trailer. Whether a ball mount shank is too small or too large to fit into a receiver tube, a CURT adapter can make up the difference. They are built with exceptional strength and designed to be precisely fitted for their application. CURT offers trailer hitch adapters to accommodate both receiver tube openings and shanks of 1-1/4″, 2″ and 2-1/2″ dimensions.
