ATI Performance Products ATI918980-87 Elastomer Ring Kit 6 in. Damper 3-Ring 87 Durometer

The ATI Performance Products ATI918980-87 is a replacement elastomer ring kit designed for ATI Super Damper harmonic balancers. This kit contains three high-quality rubber elastomer rings matched to an 87 durometer hardness rating, engineered to fit 6-inch diameter, 3-ring ATI Super Dampers.

Elastomer rings are a critical wear component inside ATI Super Dampers. Over time and with heat cycling, these rings can harden and lose their ability to dampen crankshaft torsional vibration effectively. Replacing them with the correct durometer rating restores the damper to factory performance specifications.

Key Features:

• Fits ATI 3-ring Super Dampers with a 6 in. outer diameter
• 87 durometer hardness rating for specific application tuning
• Made from high-quality rubber compound
• Direct replacement for worn or degraded OEM ATI elastomer rings
• Part of ATI's full line of Super Damper service and rebuild components

ATI offers elastomer ring kits in multiple durometer ratings to allow tuning for different engine RPM ranges and operating temperatures. Selecting the correct durometer is essential for optimal damper performance. This 87-durometer kit is a stiffer compound suited for higher-RPM or higher-temperature applications compared to the standard 70-durometer rings.
