Product details
The black Wilwood Aero6-DM supplies the right front six-piston caliper in the documented Bronco/Ranger brake package. Its 1.75/1.62/1.62-inch differential bores and nominal 1.25-inch rotor-width channel must match the installation, rather than being treated as stock-caliper dimensions. 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.
