ATI Performance Products ATI917000CS Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI917000CS Super Damper is a high-performance crankshaft harmonic balancer engineered to reduce torsional vibration and protect your engine's rotating assembly. Designed as a direct replacement or performance upgrade, ATI Super Dampers are trusted by professional racers and performance enthusiasts worldwide for their precision construction and proven durability under high-RPM conditions.

Unlike factory rubber-bonded balancers that degrade over time and lose effectiveness, the ATI Super Damper uses an elastomer ring dampening system housed in a precision-machined billet aluminum shell. This design delivers consistent, long-lasting vibration damping that helps protect crankshafts, bearings, and other internal engine components from harmful harmonic vibration.

Key Features:

• Precision-machined billet aluminum construction for lightweight strength
• Elastomer ring dampening system for consistent, reliable vibration absorption
• High-RPM rated for street, strip, and competition applications
• SFI 18.1 specification rated for safety in sanctioned racing events
• Precision inertia weight tuned to specific engine applications
• Corrosion-resistant finish for long service life
• Direct-fit replacement requiring no modifications

ATI Performance Products has been a leader in crankshaft damper technology for decades, supplying top NASCAR, NHRA, and road racing teams. The ATI917000CS Super Damper delivers the same race-proven engineering in a package suitable for high-performance street and track use.
