This CURT reducer sleeve adapter converts a 2-1/2" x 2-1/2" receiver tube opening to a 2" x 2" opening. It installs easily and is compatible with virtually any 2-1/2" x 2-1/2" hitch. Its gross trailer weight capacity and tongue weight capacity are limited to the hitch. All CURT adapters are constructed using quality manufacturing processes. Curt 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, Curt gives it a durable black carbide powder coat finish to ensure it has excellent rust, chip and UV resistance. | Curt Reducer Sleeve (2-1/2" to 2" Shank) #45405
