Wilwood Front Left Black SRP Rotor, 12.19-inch Diameter, Dual-Pattern 1.52-inch Hat

This left-hand SRP casting combines a 1.10-inch friction section with a 1.52-inch-offset hat. The 3.06-inch register centers the part, while two stud-clearance patterns allow the correct hub pattern to pass through without changing that hub. Wilwood Engineering designs and manufactures disc brake systems from its base in Camarillo, California. Bill Wood founded the company in 1977; its range now includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized uses. Selection must account for the entire 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.
