B&W Tow and Stow Receiver Hitch Ball Mounts adjust to multiple heights and eliminate the need for multiple ball mounts. These ball mounts also stow under the vehicle when not in use, protecting the hitch from garage doors and other safety risks. E-coat and powder-coat provide improved corrosion protection inside and out. // The Silencer Pad provides a cushion between the steel receiver, and steel hitch to eliminate rattle. // Made from machine forged chrome steel, the receiver lock offers a 5/8" pin with a rugged black epoxy powder coat. The 5/8" pin fits all Class III, IV, and V receiver hitches as well as prevents false locking, meaning the lock can’t just pop open. Durable and resilient, a quarter turn of the rugged tube key locks and unlocks the strongest locking pin. Plus, it boasts a water tight cap that seals out dirt and corrosion. Fits a span of 3 1/2".
