Marketed under the name "Black Ops," ITP credits overall wheel strength to its advanced manufacturing process, which transforms high-grade aluminum into incredibly lightweight, ultra tough wheels. The black SS216 and wheels feature ITP's proprietary "Rock Armor" construction, which consists of an inner reinforced lip that adds a second, inside structural component. ITP warrants the SS216 wheels against bending or breaking and offers a lifetime replacement warranty. (Depending on the machine your stock lug nuts may not work with this wheel. They MAY require a different style lug nut that we offer) Center cap included.
