Cometic C5980-60 ATI 6" Damper O-Ring Rebuild Kit 3-Ring Design

The Cometic C5980-60 is a precision-engineered rebuild kit designed specifically for ATI Super Damper harmonic balancers with a 6-inch outer diameter and 3-ring configuration. This kit is equivalent to ATI part number 918980-60 and features 60 durometer elastomer o-rings, which are the standard specification for 6-inch diameter ATI dampers.

Key Features:

• Designed for 6-inch diameter ATI Super Dampers with 3-ring design
• 60 durometer elastomer o-rings for optimal vibration dampening performance
• 0.275-inch cross-section o-rings engineered to ATI specifications
• Complete 8-piece kit includes all necessary components for proper damper restoration
• Direct replacement for worn or deteriorated elastomers in rebuildable ATI dampers
• Maintains SFI 18.1 certification when properly installed per manufacturer guidelines

ATI Super Dampers are rebuildable by design, allowing you to restore your harmonic balancer to like-new condition by replacing the elastomer o-rings that absorb crankshaft torsional vibrations. Regular inspection and replacement of these elastomers is critical for high-performance and racing applications to ensure proper engine protection. This Cometic kit provides all the precision-manufactured components needed to complete a professional damper overhaul.
