ATI Performance Products ATI916191 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916191 Super Damper is a high-performance torsional crankshaft damper engineered to control harmful harmonic vibrations that develop in the crankshaft under high-RPM and high-load conditions. Designed as a direct upgrade over the factory OEM harmonic balancer, the ATI Super Damper helps protect rotating assembly components and extend engine life in performance street and racing applications.

ATI Super Dampers utilize a precision-machined billet aluminum hub paired with a bonded elastomeric ring and an inertia ring, providing superior torsional dampening across a wide RPM range. Unlike standard rubber-bonded OEM balancers that degrade over time and can fail catastrophically, the ATI Super Damper is rebuildable and re-tunable, allowing racers and engine builders to adjust the inertia ring to match specific engine combinations.

Key Features:

• Precision-machined billet aluminum construction for strength and reduced weight
• Rebuildable and re-tunable design for long service life
• Controls crankshaft torsional vibration to protect engine components
• SFI 18.1 specification compliant for sanctioned racing use
• Multiple timing marks for accurate ignition timing setup
• Compatible with front accessory drive and belt systems
• Designed for performance street, drag racing, and competition applications

ATI Performance Products has been a trusted name in professional motorsports for decades, with Super Dampers used across NASCAR, NHRA, IHRA, and countless grassroots racing programs. The ATI916191 delivers the same race-proven technology in a bolt-on package built for demanding performance use.
