Product details
Black powder coating finishes this four-piston DynaPro radial caliper. Its aluminum pistons have dust boots, and the 1.25-inch bores provide the smaller 2.46-square-inch area option in this body format. The nominal 0.81-inch rotor opening is a thickness dimension and should be checked separately from rotor diameter. 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
Compare the exact caliper version, pad profile and rotor offset with the installed assembly. The 5.98-inch radial mount needs a bracket with the correct height and stand-off. Check wheel-spoke clearance around the body and fitting, and preserve a bleed arrangement that permits air to leave the hydraulic chamber.
