Wilwood Red Six-Piston Front Kit, SRP 14-Inch Rotors, Jeep Wrangler/Wrangler JK (2007–2018)

Red Superlite 6R calipers and drilled/slotted 14-inch rotors form this Wilwood front brake package for the stated Jeep Wrangler JK range. The rotor rings use 72 curved vanes, with separate hats carrying them on the original hubs. This conversion includes the matching radial brackets and BP-20 pads, so it should be selected as a complete brake combination for the specified factory-spindle layout. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.
