Product details
The bubble-flare socket is the defining interface on this Wilwood chassis adapter. It couples an M10 x 1 hard line to a male -3 hose connection using a zinc-plated steel body. Founded in 1977 under Bill Wood, Wilwood Engineering operates from Camarillo, California. The company designs and manufactures disc braking systems and components, including calipers, master cylinders, brake rotors, fittings, valves and brake lines. Its motorsport, specialized and street-performance range requires individual parts matched to the complete braking arrangement.
