Product details
This anodized front right Wilwood Aero6-DM is the caliper used in the specified 2021–2024 Ford Bronco and 2019–2022 Ranger direct-mount brake arrangements. Six stainless pistons work in a forged body with 7.48-inch lug centers; it is a single replacement component, not the complete conversion kit. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems for motorsport, street-performance and specialized use, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.
