Product details
This front hub is specified for a Mopar B-Body drum-spindle brake conversion. It accepts a separate rotor hat retained at three threaded points; confirm the assembly dimensions rather than choosing by wheel pattern alone. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.
