Product details
This front Wilwood hub combines the 1973–1976 Mopar A-Body disc-spindle bearing arrangement with solid-rotor offset geometry. It is a conversion component for the matching Wilwood brake assembly, rather than a complete brake kit. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. Its disc-brake systems and components include calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with each component selected for the complete brake system.
