The GT rotor option pairs red Superlite 6R calipers with 14-inch directional rotor rings and aluminum mounting hats. Separate hubs and bearing hardware are part of the front package for the specified F-100 drum spindle. Wilwood Engineering, established by Bill Wood in 1977 and based today in Camarillo, California, manufactures and designs disc brake systems and their components. The product range covers brake rotors, calipers, valves, master cylinders, brake lines and fittings for motorsport, specialized and street-performance applications. Suitability depends on matching each component to the entire brake system.

Fitment & Compatibility

Confirm the truck is the listed 1968–1972 4x2 application and retains the required factory drum spindle. Compare the full wheel envelope with DS1267, then select the hydraulic connections separately. A four-wheel-drive or altered spindle must not be assumed compatible.

Check the application-specific restrictions for F-100. A shared model name does not replace the exact year and brake/suspension configuration. 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.
