The Rusty's Crossmember is a direct replacement for those that have been beat and banged on rocks and stumps. Made of 3/16 steel, pre-drilled for easier installation of our engine - trans skid and our TC skid. It is also available with a 1 inch drop model for better driveline angles without loosing any ground clearance. If used in conjunction with our engine skid plate, new holes will need to be drilled. There is no change on the catalytic converter attachment and we actually recommend cutting that off. Black powder coated for durability.
