    Wilwood 140-14974 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.

    Specs

    Our rotors are machined and fully e-coated, just like the rotor hats. This is a protectant coating the prohibits surface rust from forming on the exposed surfaces. Once the parts are installed and being bedded in, the brake pad friction and caliper pressure will remove the coating at the spot the brake pads touch. This will expose the silver iron material underneath.
