Product details
This combination seal pack contains eight pieces for piston-pressure and dust-seal maintenance. The manufacturer lists a 1.620-inch ring inside diameter and 0.099-inch square-ring thickness. It is the specific combined kit, rather than a set of piston rings alone, for a matching Wilwood service application. 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
Check the caliper’s exact replacement-kit reference and dust-seal arrangement. Matching a nominal bore without comparing the groove and protective-seal profile is insufficient. Establish the needed service quantity from the actual caliper assembly and inspect the remaining pistons and hardware as part of the repair.
