Product details
Four 1.25-inch aluminum pistons with dust boots are fitted to this black-anodized DynaPro radial caliper. It is the nominal 0.81-inch rotor-width configuration, with a published 2.46-square-inch piston area. The finish and booted piston arrangement identify the selected component within the broader radial-mount range. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility
Use the 5.98-inch radial centers together with the 1.61-inch mounting height to compare the receiving bracket. Rotor thickness, lateral offset and pad sweep must all match. Confirm the brake circuit’s hydraulic sizing and the available wheel space before substituting for a larger-bore or unbooted DynaPro.
