Wilwood 140-12569 D154 Pro-Series Rear Disc Brake Kit Chevrolet C10 GMC C15

The Wilwood 140-12569 D154 Rear Disc Brake Kit is designed for select Chevrolet and GMC truck applications using the compatible 5-lug rear axle configuration with a 2.42-inch offset. The system features 12.19-inch UltraLite HP 32 rotors with hats and D154 2-piston calipers finished in black powder coat.

This rear brake package is application-specific and requires careful verification of axle offset, bolt pattern and wheel clearance before installation. Some 15-inch wheels may be compatible, but wheel clearance must be checked using the applicable Wilwood installation diagram before purchase.
