Product details
The GN square-ring kit supplies six piston seals of the listed 1.620-inch inside diameter. It is the six-piece pack in this size, which should be distinguished from a four-piece service set with similar dimensions. The manufacturer’s 210M material code and 0.099-inch section belong to the ring specification. 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 precise GN caliper reference and its assigned seal kit, including the quantity of service locations. Check the square groove profile before replacing rings. A matching diameter and pack count do not establish interchangeability with another caliper family or supply the rest of the components needed for a complete overhaul.
