Wilwood Front Black SRP Dynapro Hub Kit, Dodge/Plymouth B/E-Body Drum Spindles (1962–1972), 12.19-Inch

Black six-piston Dynapro calipers clamp drilled/slotted 12.19-inch rotors in this Wilwood Mopar conversion. Replacement hubs are configured for the specified B/E-body drum-spindle arrangement, with a +0.17-inch wheel mounting change. The rotor and caliper package therefore needs both a spindle check and a wheel-position assessment. 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

Match the individual Dodge/Plymouth model and year to DS642 rather than assuming every B/E-body spindle is the same. A conversion from four-bolt to two-bolt master-cylinder mounting needs the separately sourced adapter; retaining a compatible existing cylinder is a different case. Hydraulic lines are not included. Verify hub registration and compare the actual wheel's barrel and spoke geometry with the clearance template.

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