Wilwood Front Superlite 6R Kit for 2007–2018 Jeep Wrangler/JK, Black Calipers and 12.88-Inch Rotors

The listed Jeep JK front hub accepts this 12.88-inch Superlite 6R conversion. Black six-piston calipers and two-piece slotted rotor assemblies replace the service-brake components while the original hub remains in use. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.
