Product details
This red DynaPro supplies the 1.75-inch stainless piston option in a forged four-piston lug body. Its nominal 0.81-inch rotor opening is intended for the corresponding brake package. Finish identifies the visible variant, while the rotor width, piston area and 5.25-inch lug spacing govern selection. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.

Fitment & Compatibility
Compare the exact caliper and bracket drawings when replacing another DynaPro. Check rotor diameter and pad alignment as well as the 0.75–0.83-inch thickness envelope. Confirm the hydraulic inlet and available wheel space, and evaluate the master cylinder and opposite axle before changing piston area.
