Product details

Red powder coat surrounds the forged body of this Wilwood Dynapro Low-Profile caliper. Its four 1.38-inch pistons provide 3.00 square inches of effective area, while the low-profile bridge and top-retained pads address installations with restricted outboard space. 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.
