Ultimate Wrangler stopping power! This brake kit is available as an option on all of our 1 ton TJ and JK Wrangler frontend packages, but it is also available as a retrofit kit to any of our frontends that use the F-350/F-450 style iron 1 ton outer knuckle. This kit includes 13" one piece rotors drilled to 5 on 5 1/2" wheel bolt pattern, dual piston calipers, and our complete heavy duty steel bracket kit. All brackets are zinc plate finished, and all necessary hardware is included.
