Product details
The 1955-1957 Chevrolet spindle application of this Wilwood front hub uses an intermediate adapter to mount a vented rotor. Its bare aluminum construction and two five-lug wheel bolt circles are specified for a custom brake assembly rather than an integral replacement rotor. Wilwood's range extends from calipers and brake rotors to master cylinders, valves, fittings, and brake lines, all selected to meet the requirements of a complete brake system. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California and designs and manufactures disc brake systems for motorsport, street-performance, and specialized uses.

Fitment & Compatibility
