Product details
Red powder coat distinguishes this D8-4 front caliper for the 1965–1982 Chevrolet Corvette. The four-piston layout matches the original front caliper's hydraulic volume while replacing its cast iron body with forged aluminum. This component comes from Wilwood Engineering, established in 1977 by Bill Wood and based in Camarillo, California. Its disc brake design and manufacturing work includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized systems.
