Wilwood Front Red Plain-Rotor Dynapro Hub Kit, Early Ford Drum-Spindle Cars/Trucks (1937–1948), 12.19-Inch

Red six-piston Dynapro calipers and plain 12.19-inch rotors form this Wilwood early-Ford front conversion. The package supplies replacement hubs for the specified original drum-spindle geometry. It does not establish compatibility with every aftermarket axle simply because that axle is installed in an early Ford body. 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 exact model/year and body-style entry, then inspect the spindle and bearing fit against DS641. Confirm wheel-stud pattern and hub registration before installation. Choose suitable hydraulic hoses and evaluate the existing master-cylinder/pedal pushrod arrangement. Check radial and axial clearance with the wheel drawing, and verify rotor centering before the brake test.

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