CURT reducer sleeves 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 reducer sleeve adapter can make up the difference. Our reducer sleeve adapters are built with exceptional strength and designed to be precisely fitted for their application. This CURT reducer sleeve adapter converts a 3" x 3" receiver tube opening to a 2" x 2" opening. It installs easily and is compatible with virtually any 3" hitch. Its gross trailer weight capacity and tongue weight capacity are limited to the hitch. 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 carbide powder coat finish to ensure it has excellent rust, chip and UV resistance.
