Product details
Black powder coating finishes this 3.25-inch-mount DynaPro Single caliper. It has two opposed 1.75-inch stainless pistons, despite the series’ Single name. The compact billet body is the 0.38-inch nominal rotor-width version, intended for an assembly whose pad, rotor and hydraulic dimensions have been matched. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility
Check the exact bracket spacing and rotor centerline before replacing another DPS. The permitted 0.25–0.38-inch rotor thickness range and 6.00–13.00-inch diameter envelope are separate checks. Allow room for the NPT fitting, pad access and wheel spokes, and retain a suitable hydraulic balance with the other brakes.
For help identifying the correct brake component, provide the caliper markings and installation dimensions. PMB Performance has over 20 years of experience with parts and brake-system details.
