ATI Performance Products ATI916549 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916549 Super Damper is a high-performance crankshaft harmonic balancer engineered to reduce torsional vibration and protect your engine's crankshaft, bearings, and rotating assembly under demanding performance and racing conditions. ATI's Super Damper series is the industry standard in professional motorsports, trusted by drag racers, road racers, and serious performance enthusiasts worldwide.

Unlike factory rubber-bonded balancers that degrade over time and lose effectiveness, the ATI Super Damper uses a precision-machined billet aluminum housing with an inertia ring tuned via elastomer rings to provide consistent, reliable damping across a wide RPM range. This design also allows for field re-tuning by swapping elastomer rings to match specific engine builds and operating conditions.

Key Features:

• Precision billet aluminum construction for durability and reduced rotating weight
• Elastomer-tuned inertia ring for superior torsional vibration damping
• Re-tunable design — elastomer rings can be changed to match engine specifications
• Machined timing marks for accurate ignition timing reference
• SFI 18.1 certified for sanctioned racing applications
• Significantly stronger and more reliable than OEM rubber-bonded balancers
• Direct bolt-on replacement fit for compatible engine applications

ATI Performance Products has been manufacturing championship-winning drivetrain components since 1966. The Super Damper line is a proven upgrade for any performance build where engine longevity and power protection are a priority.
