Wilwood Drilled 14-Inch Front Disc Conversion with Black Superlite Calipers and Hubs for Ford F-100 4x2 Drum Spindles (1968–1972)

Drilled-and-slotted Spec-37 rotor rings identify this Superlite front package for the specified F-100 spindle. Black radial-mount calipers operate the service brakes, with wheel hubs, bearings, mounting hats and brackets supplied for the conversion. Founded in 1977 by Bill Wood, Wilwood Engineering is now based in Camarillo, California, where its work centers on disc brake systems and components. Calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized installations; selecting these parts requires considering the complete braking system.

Fitment & Compatibility

Identify the original drum spindle before selecting by F-100 model year. DS1267 governs the 1968–1972 4x2 mounting configuration, hub assembly and wheel clearance. Order a suitable separate front flexline set and check movement through full steering travel.

The application list names F-100. Verify the particular year and suspension/brake option for each model. Use the fitment table below to confirm year, model, trim and brake or suspension options.

PMB Performance has over 20 years of experience with parts and fitment details. Contact us with the original vehicle specification and any changes to its braking or suspension system.

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