Product details

Red four-piston calipers clamp 14-inch SRP rear rotors on the measured G-Body flange. Plan the required housing work and parking cable connection. The conversion combines the caliper, pad and rotor configuration specified for this axle and mounting arrangement. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its product range includes brake rotors, calipers, master cylinders, valves, fittings and brake lines, selected individually to match the complete brake system.

Fitment & Compatibility

Select this rear conversion by the GM G-Body housing flange and measured 2.62-inch axle offset. Installation requires substantial housing-flange material removal and drilling two holes as shown in DS-1571; a qualified machine shop is recommended. Parking-brake cables and their connection hardware are separate. Check shock-mount interference, axle registration and clearance around the 14-inch rotors and calipers.
