Wilwood Red Superlite 6R Front Brake Kit, Drilled 14-Inch Rotors and Aluminum Hubs, Ford F-100 4x2 (1968–1972)

Red six-piston calipers clamp the drilled-and-slotted rotor rings in this F-100 front conversion. The two-piece rotors mount through aluminum hats to the supplied hubs, with the retained drum spindles determining the mechanical fit. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc braking systems and components for street-performance, motorsport and specialized use. Its calipers, rotors, master cylinders, valves, fittings and brake lines are chosen around the hydraulic, mounting and balance needs of a complete system.

Fitment & Compatibility

Use only the documented 1968–1972 F-100 4x2 spindle arrangement. Check bearing seats, the selected wheel bolt circle and caliper-to-spoke clearance against DS1267. Neither the original spindle nor the vehicle-end hydraulic hoses are replaced by supplied components.

Listed model families are F-100; the individual year and brake/spindle conditions remain decisive. Use the fitment table below to confirm year, model, trim and brake or suspension options.

With more than 20 years of parts experience, PMB Performance can help review the specified brake arrangement. Include the vehicle year and details of any hub, spindle or suspension changes.

Check the Installation instructions for the full assembly and wheel-clearance requirements.
