Product details
Designed around the 1973-1976 Mopar A-Body disc-brake spindle application, this Wilwood hub supports an adapter-mounted vented rotor. It is the vented-offset option for the conversion and should be selected with the intended rotor and caliper bracket geometry. Wilwood Engineering designs and manufactures complete disc brake systems as well as calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Based in Camarillo, California, it was founded by Bill Wood in 1977. The range serves motorsport, street-performance, and specialized applications, requiring each part to be matched to the system in which it operates.
