Product details

This Wrangler JK rear kit uses black FNSL4R calipers and 13.50-inch GT-slotted brake rotors while retaining the factory parking brake. BP-22 pads and the specified 20-inch hose set accompany the four-piston service-brake hardware. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Founded by Bill Wood in 1977, the company also produces the individual calipers, brake rotors, master cylinders, valves, fittings and brake lines used in these installations. Selection should account for how each component works within the complete brake system.
