Product details

The red GT configuration supplies the larger 14-inch rear rotor assembly for a matched New Style Bronco axle. Four-piston Superlite service calipers work alongside the internal-shoe mechanical parking brake, with iron hats supporting the separate rotor rings. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines, with each component chosen to suit the complete brake system.

Fitment & Compatibility

Measure the housing end and bearing arrangement, and verify the 2.36-inch axle offset. This is the New Style flange version, not the 2.00-inch Big Ford package. Check wheel-to-caliper clearance and choose the correct hydraulic and parking-control connections separately.
