    Details

    Wilwood's Classic Series front disc brake kits for Chevrolet and GMC 1/2 ton trucks from 1951 to 1959 offer disc brake upgrade solutions for OEM Drum spindles. A completely new kit design, featuring a one-piece 11.86" x 1.10” rotor and hub assembly with a dual 5 x 4.75" and 5 x 5.00" wheel bolt circle. Based on the venerable Forged Billet Dynapro 6 caliper, these versatile kits are easily optioned to suit the braking requirements and style preferences for a daily driver or the most discriminating show enthusiast. Intended vehicle applications require no modifications for installation, and should provide plenty of clearance inside popular 15" wheels. DP6 1 piece kits can be used with either manual or power boost master cylinders. Kits come complete with calipers, rotors and hub assembly, brackets, brake line kit, and hardware.
