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. Our adapters are built with exceptional strength and designed to be precisely fitted for their application. It installs easily and provides 4 Inch of extra clearance for a bumper or spare tire. It has a gross trailer weight capacity of 3,500 Pound and a tongue weight capacity of 350 Pound. All CURT adapters are constructed using our quality manufacturing processes. We CNC-form each unit, weld it together using advanced robotic systems and then mechanically descale every surface to make each adapter smooth to accept a finishing coat. To finish off this adapter, we give it a durable black powder coat finish to ensure it has excellent rust, chip and UV resistance.
