Product details
The black rear D8-4 is a replacement caliper for 1965–1982 Chevrolet Corvettes retaining their factory brake arrangement. Its four 1.38-inch pistons provide a 3.00-square-inch effective area, with a forged housing and original-style D8 pad fit. Wilwood Engineering is a Camarillo, California-based designer and manufacturer of disc brake systems, founded by Bill Wood in 1977. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications.

Fitment & Compatibility
The rear bracket must match the 5.16-inch lug centers. A matching flex line is required for the 1/8-27 NPT inlet, and the wheel must clear the caliper across the entire assembly rather than only at its outside diameter.
