Wilwood GT Slotted-Rotor Front Conversion for F-150/F-150 Heritage/Navigator/Blackwood (1997–2004), Red Calipers, 14.25-Inch Rotors

GT Slotted friction surfaces define this red-caliper version of Wilwood's 14.25-inch front brake package for the listed Ford and Lincoln trucks. AERO6 calipers use six pistons and the kit-specific mounting components, with application-matched lines included. Selecting the correct original five-lug two-wheel-drive suspension and hub arrangement is essential; the package does not establish universal fitment across these truck model names. 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

Use the separate vehicle rows to confirm production year, rear disc or drum equipment and the Heritage restriction. Check any replacement spindle or modified hub against the manufacturer's installation geometry. Assemble the hat and rotor hardware as instructed and confirm the caliper follows the rotor centerline. The clearance template must be compared with the actual wheel, including spoke offset. Verify flexible-line freedom throughout steering travel and review pedal travel and proportioning with the rear brakes before returning the vehicle to service.

Match the individual year, model, submodel and equipment conditions in the fitment table below.
