Product details
This 12.88-inch Superlite rear conversion is the Big Ford Bronco version with 2.00 inches of axle offset. Black four-piston calipers operate the GT rotor rings, while the iron hats and internal shoes provide a separate mechanical parking system. Camarillo, California is the home of Wilwood Engineering, the disc brake systems and components manufacturer founded by Bill Wood in 1977. It designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. The requirements of the complete brake system determine which individual components are appropriate.
