Wilwood D52 Front 2-Piston Brake Caliper Kit - Red (2.00in Pistons, 1.04in Rotor) for Select GM 1969-2002

Fits select 1969-2002 GM passenger vehicles and trucks, including Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac models. This kit is a direct bolt-on upgrade designed to replace the original single-piston calipers with a high-performance dual-piston setup.

The Wilwood D52 kit features forged billet aluminum bodies and stainless steel pistons, providing a significant weight reduction over heavy cast-iron factory units. These materials, combined with competition-style high-temperature seals, eliminate common OE issues like rust, bore pitting, and seal failure. Engineered for both street and track use, the calipers maintain original front-to-rear brake bias when used with the factory master cylinder, providing 6.28 square inches of piston area per caliper. These units mount in the factory location over stock rotors and utilize original D52-style brake pads.
