Wilwood Caliper-D8-4 Rear Black 1.38in Pistons 1.25in Disc

D8-4 rear calipers are a direct bolt-on replacement for the OE factory rear calipers on all 1965-82 Corvettes. Forged billet aluminum bodies, stainless steel pistons, and high temperature seals put an end to the rust, bore pitting, and seal failures that plague the original cast iron caliper design.
