Product details

The Wilwood Dynapro-ST Radial uses four 1.75-inch Thermlock pistons to limit heat transfer from the pads into the caliper, fluid and seals. This Type III anodized forged aluminum version includes dust boots, a 5.98-inch radial mounting pattern and a nominal 0.81-inch rotor-width specification. It is a single hydraulic caliper for a matching rotor and bracket arrangement. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Check the caliper-to-bracket attachment and rotor offset before ordering. Changing piston diameter changes hydraulic requirements even when a different caliper shares the same bolt spacing.

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

The four-piston Dynapro-ST uses Thermlock insulated pistons to limit heat transfer from pads into the caliper, fluid and seals. Its radial mount and type 7816 pads must be combined with the specified rotor width and installation geometry.
