Product details
This four-piece square-ring kit uses the listed 1.620-inch inside diameter and 0.099-inch section. It is a defined piston-seal service pack and should be distinguished from six-piece or dust-seal combination sets using similar size labels. The exact caliper parts listing identifies where these rings belong. 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
Match the caliper and kit reference, then compare the square groove profile before installing replacement seals. The ring measurements are not universal fitment for every caliper carrying a similar piston-bore designation. Inspect bore condition, pistons and other sealing locations separately and order the quantity required by the service arrangement.
