Product details
The black GTB finish and slotted face are combined with the 1.52-inch hat geometry in this casting. Its 12.19 x 1.10-inch friction ring remains non-directional, with dual five-lug clearance holes for the correctly matched hub. The manufacturer is Wilwood Engineering of Camarillo, California, founded by Bill Wood in 1977. It designs and manufactures disc brake systems, supplying calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. Matching this component requires consideration of the complete brake system.

Fitment & Compatibility
Front replacement rotor for the matching 1963–1987 Chevrolet C10 conversion using the specified Wilwood ProSpindle and five-lug hub. DS-1365 requires the correct later ball joints for earlier trucks and later tie-rod ends for 1971–1972 applications. The 1.52-inch hat and dual clearance patterns do not make this a stock-spindle replacement.
