The ATI elastomer replacement kit is a three-ring service set created to rebuild a harmonic crankshaft damper. This variant lists a Viton outer ring with 60/70/70 staging for the ring stack, offering a heat-resistant outer element in assemblies that require it. The kit replaces worn elastomers to restore damping behavior without replacing the entire damper hub, keeping repair practical and component-matched.
