Wilwood Right DP6A Anodized Caliper, 1.62/1.38/1.38-Inch Bores / 0.81-Inch Rotor Width

The right Forged Dynapro 6A uses a triple-bridge forged body with six stainless pistons. This hard-anodized version combines 1.62/1.38/1.38-inch bores with a nominal 0.81-inch rotor-width cavity and 5.25-inch lug attachment. Bill Wood founded Wilwood Engineering in 1977, and the company is based in Camarillo, California. It designs and manufactures disc brake systems and a component range of calipers, brake rotors, master cylinders, valves, fittings and brake lines serving motorsport, street-performance and specialized installations.

Fitment & Compatibility

Compare rotor thickness with the 0.75–0.83-inch permitted range before replacing another DP6A. Verify the 2.03-inch mount height, type 6712 pads and right-side orientation, then check the existing system’s piston-area requirement.
