Wilwood - D52-R GM Full Size Single Piston Brake Calipers

Wilwood – D52-R GM Full Size Single Piston Brake Calipers

The Wilwood D52-R GM Full Size Single Piston Brake Caliper is Wilwood’s newest race-focused evolution of the traditional GM full-size caliper. It features a forged aluminum body with a Type III hard-anodized finish and a stainless steel piston, delivering lower deflection and higher volumetric efficiency than heavier cast-iron competitors.

This lineup offers 2.75" or 2.38" piston options, supports rotor widths from 0.81" to 1.25", and accommodates rotor diameters up to 12.19". The centered fluid inlet port, positioned directly behind the piston, eliminates interference with slide pins for a cleaner installation.

These calipers use D52-style full-size brake pads and mount with stock height and offset. Calipers are universal left or right. Note: Slide pins and vibration dampeners are not included.
