Product details
This Superlite square-ring pack groups four piston seals in the listed 1.750/1.620-inch size arrangement. A 0.099-inch section is specified for the hydraulic rings. It is a mixed-size service component whose larger and smaller positions must correspond to the exact caliper being repaired. 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 full Superlite reference and assigned kit, since the family includes different piston configurations. Compare the seal groove and keep each size identified during fitting. Any worn piston, damaged bore, dust-protection component or mechanical hardware needs to be evaluated separately from replacing the seals supplied in this pack.
For help identifying the correct brake component, provide the caliper markings and installation dimensions. PMB Performance has over 20 years of experience with parts and brake-system details.
