Product details
The smallest-bore DynaPro in this lug-mount group uses four 1.00-inch stainless pistons. Its black forged body is configured for a nominal 0.81-inch-wide rotor, with a published piston area of 1.58 square inches. This is a specific hydraulic choice rather than a universal alternative to a larger-piston DynaPro. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake systems and components serve motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among its products, selected according to the complete brake system’s requirements.

Fitment & Compatibility
Match the intended master-cylinder and axle balance requirements before using the smaller bores. Confirm the 5.25-inch lug spacing, 2.10-inch mount height and rotor offset. Check pad position on a rotor of suitable diameter and thickness, then inspect clearance to the wheel, inlet fitting and brake hose.
