Product details

Fit rear hydraulic braking and internal parking shoes to a verified GM G-Body axle. This red-caliper GT package needs wheel and flange checks. The conversion combines the caliper, pad and rotor configuration specified for this axle and mounting arrangement. Wilwood Engineering was established in 1977 by Bill Wood and is based in Camarillo, California. Disc brake systems and components are its focus, from brake rotors and calipers to master cylinders, valves, brake lines and fittings. Its work spans motorsport, street-performance and specialized applications, with the complete brake system determining the correct individual components.

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.
