Wilwood Front Red Plain-Rotor Hub Conversion for Dodge/Plymouth B/E Drum Spindles (1962–1972), Dynapro 6

Plain 12.19-inch vented rotors and red six-piston Dynapro calipers form this Wilwood Mopar front hub kit. It adapts the specified B/E-body drum-spindle arrangement using replacement hubs and mounting brackets. The selected geometry shifts wheel mounting +0.17 inches from the stated OE reference. 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

Check the exact Dodge/Plymouth model row and spindle against DS642, with attention to the B/E-body production years. A two-bolt master cylinder installed in place of the four-bolt original needs the separately sourced mounting adapter. This is conditional on that hydraulic conversion, not an instruction to replace a compatible cylinder. Provide hoses and verify wheel radius, spoke depth and tire position before assembly.

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