Product Description

The Wilwood 140-15940-D brings six-piston Superlite braking to 1963-1987 Chevy C10 and C15 trucks, built around Wilwood's iron ProSpindle for a purpose-engineered fit rather than a generic bolt-on. The forged narrow caliper body keeps weight in check while the 12.19" slotted and cross-drilled rotor handles heat well under repeated hard stops.

Because the kit is application-specific and requires the matching ProSpindle, installation is more involved than a simple caliper swap, but the payoff is a clean, properly engineered big brake setup that's fully compatible with the factory master cylinder. Just make sure your wheels clear 17" and larger before committing to this kit.
