ATI Performance Products ATI918970-70 Elastomer Ring Kit 2-Ring 7 Inch 70/70/70 Durometer

The ATI Performance Products ATI918970-70 is a high-quality elastomer replacement ring kit designed specifically for ATI Super Damper harmonic balancers. This 2-ring configuration is engineered for 7-inch diameter dampers and features a 70/70/70 durometer rating (outer ring/inner ring/face) to provide optimal vibration damping characteristics for high-performance and racing applications.

Key Features:

• Precision-machined elastomer O-rings made from high-quality rubber compound
• 2-ring design for 7-inch diameter ATI Super Dampers
• 70/70/70 durometer rating provides balanced damping across all three contact surfaces
• Designed to eliminate harmful crankshaft harmonics and parasitic power loss
• Rebuildable solution extends the life of your ATI harmonic balancer
• Tested to over 3 million cycles in professional racing competition
• Compatible with steel damper shells

ATI's patented elastomer Super Damper design uses unbonded O-rings installed in computer-machined grooves on the inertia weight, creating an effective dual-damper system. When your existing elastomer rings show signs of wear, this replacement kit restores your damper to like-new performance specifications. Essential maintenance for engines operating above 6,000 RPM and high-performance street applications where crankshaft harmonic control is critical.
