Wilwood Front GT Rotor/Hub Conversion, Red AERO6 Calipers and 1.25-Inch Rotor Thickness, for Ford F-100 4x2 (1968–1972)

Red AERO6 calipers and GT-slotted rotor rings provide the service-brake components of this F-100 front kit. The 14 x 1.25-inch rotors attach to separate hats and supplied hubs while the original drum spindles are retained. Founded by Bill Wood in 1977, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems plus their individual components. Its work serves specialized applications, motorsport and street-performance vehicles, with a range of calipers, brake rotors, master cylinders, valves, fittings and brake lines. A compatible complete system governs the selection of each part.

Fitment & Compatibility

Check the exact drum-spindle and bearing layout rather than treating every F-100 front axle as identical. The verified application is 1968–1972 4x2. Follow DS1268 for the wheel-clearance and hub checks, and supply appropriate flexible hydraulic lines.

Models represented in the detailed applications: F-100. Each is subject to its individual year, trim and brake/suspension condition. Use the fitment table below to confirm year, model, trim and brake or suspension options.

PMB Performance brings over 20 years of parts and fitment experience. Send the vehicle details and installed brake/suspension configuration if you need help checking this package.
