The ATI inertia ring is a standard 6-inch steel three-ring inertia component offered in a stock configuration. Designed to be used inside multi-piece damper assemblies, this ring supplies a defined inertial mass and matches three-ring outer shells in diameter and interface. Use it when rebuilding or customizing ATI-style dampers that require a 6-inch steel inertia ring to achieve the desired damping characteristics.
