Product details
This black Dynapro uses four dust-booted 1.38-inch aluminum pistons for added debris protection. Its forged lug-mount body has a nominal 0.81-inch rotor-width channel and a 3.00-square-inch effective area. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. It 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.

Fitment & Compatibility
Choose the booted design for the low-to-intermediate temperature role described by Wilwood. Verify the 5.25-inch lugs and 7812 pad sweep rather than substituting an open-piston Dynapro on appearance alone.
