Wilwood DynaPro 6 12.19in Drilled Red Front Big Brake Hub Kit - Chevrolet Bel Air 1955-1957

The Wilwood DynaPro 6 front big brake hub kit combines forged billet aluminum six-piston calipers with 12.19 inch vented rotors and forged front hubs, an intermediate six-piston upgrade for non-ABS spindle muscle cars and street rods. It adds brake capacity and pad performance over four-piston kits while clearing smaller wheels than the 14 inch systems. Drilled or plain rotor faces and multiple caliper finishes are available to match the build.
