ATI Performance Products ATI916017 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916017 Super Damper is a precision-engineered torsional crankshaft damper designed for high-performance and racing applications. ATI Super Dampers replace the factory harmonic balancer with a superior unit that controls destructive crankshaft torsional vibrations, protecting the engine from premature wear and catastrophic failure under high-RPM and high-horsepower conditions.

Unlike rubber-bonded OEM-style balancers that degrade over time and lose their dampening effectiveness, ATI Super Dampers utilize a precision-machined, multi-ring elastomeric dampening system that remains consistent across a wide RPM range. This design is SFI 18.1 certified, meeting the safety standards required for many sanctioned racing events.

• SFI 18.1 certified for sanctioned racing compliance
• Precision-machined billet aluminum construction
• Multi-ring elastomeric torsional dampening system
