Product details
This right HD rotor provides the thinner 0.81-inch working section with smooth friction faces. Its 36 curved vanes and Spec-37 iron casting suit a dimensionally matched system that needs high-temperature capability without GT face slots. For this rotor, the manufacturer is Wilwood Engineering, founded in 1977 by Bill Wood and based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized products are selected to satisfy the complete brake system's requirements.

Fitment & Compatibility
Installation requires a hat or hub designed for the 6.38-inch rotor register and 8 x 7.00-inch attachment. Verify wheel clearance around the complete caliper, along with the rotor's 0.81-inch width. The ring alone does not define a direct-fit vehicle or axle application. Select pads and operating duty to suit the rotor material and the intended brake system.
