Wilwood Right MC4 Anodized Parking Caliper, Left-Hand Lever / Offset Plate with 2.00-Inch Hole Centers

This right-hand Wilwood MC4 pairs the caliper body with a left-hand cable lever. The dedicated offset plate has mounting holes on 2.00-inch centers, while the mechanical piston and return spring provide parking operation on a nominal 0.81-inch-wide rotor. 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.
