Wilwood Front Red Dynapro SRP Conversion, Dodge/Plymouth B/E-Body Drum-Spindle Cars (1962–1972)

Red Dynapro 6 calipers and drilled/slotted 12.19-inch rotors distinguish this Wilwood Dodge/Plymouth front package. The replacement hubs and brackets are for the listed original drum spindles. Six-piston caliper clearance and the +0.17-inch wheel mounting change both need to be checked on the completed car. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Follow the model/year and B/E-body spindle qualifications in DS642. Check the wheel-stud pattern and hub register before assembly. If the chosen master cylinder changes from the original four-bolt to a two-bolt mounting pattern, arrange the required adapter separately; the brake kit does not supply it. Select compatible hoses and verify the full wheel drawing before testing hydraulic travel and brake balance.

Match the individual model, year, submodel and brake configuration in the fitment table below.
