Product details
A 0.860-inch offset distinguishes this GT rotor from other 13.38-inch truck rotors. It is the integral-hat replacement used in the corresponding Ford Bronco and Ranger AERO6-DM front packages, with 48 vanes and a 1.25-inch friction section. Bill Wood established Wilwood in 1977. From Camarillo, California, the company designs and manufactures disc brake systems covering motorsport, street performance and specialized applications, with calipers, rotors, master cylinders, valves, fittings and lines in its product range. This rotor should be selected with the mounting arrangement, friction compound and hydraulic system in mind.
