Wilwood Type III Anodized Dynapro Radial Dust Seal, 4-Piston Caliper for 0.81-Inch-wide Rotor with 5.98-Inch Radial Centers

For a brake system using a 0.81-inch-wide rotor, this Type III anodized Wilwood Dynapro Radial Dust Seal provides 4 pistons with 1.25-inch bores. The caliper attaches on 5.98-inch radial centers. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, master cylinders, valves, fittings and brake lines.

This four-piston radial Dynapro includes piston dust wipers. The radial mounting centers are common to several rotor-width and radius versions, so bracket height, pad sweep and actual rotor dimensions must all be compared.

Fitment & Compatibility

Measure rotor width before comparing calipers. Verify the mount height, rotor centerline and available wheel space; a common piston count does not establish interchangeability.

This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
