Product details
A six-lug wheel flange distinguishes this Chevrolet C10/C15 front hat hub. The separate rotor hat, spindle bearings and three retention screws belong to the documented conversion; wheel pattern alone cannot establish fitment. Founded by Bill Wood in 1977, Wilwood Engineering designs and manufactures disc brake systems from Camarillo, California. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications. Individual components must be selected for the complete brake system.
