Product details
The 1973–1976 Mopar A-Body disc-spindle application uses a hat-mounted rotor with this hub. Bearing references differ from the adapter-mount alternative, making the complete spindle interface an essential check. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.
