Product details
The GNX4 square-ring kit groups four piston seals of the listed 1.880-inch inside diameter. Each uses the 0.099-inch section specified for this pack, with manufacturer material code 210M. It is intended for a matching caliper’s seal service rather than as a dimension-only universal repair kit. 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
Confirm the kit reference against the caliper’s own service listing and compare the square groove profile. A similarly sized round seal is a different component. Establish the number of packs required from the actual caliper arrangement, then inspect the other hydraulic and mechanical components separately during the repair.
