Product details
This Wilwood A4 inner cup locates in a 1.980-inch front hub bearing bore. It supplies the tapered running track for the designated cone and should not be confused with an outer race of a similar diameter. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance, and specialized applications. Bill Wood founded the company in 1977. Its range covers brake calipers, rotors, master cylinders, valves, fittings, and lines, which are selected according to the needs of the complete system.
