ATI Performance Products ATI917275 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI917275 Super Damper is a high-performance torsional crankshaft damper engineered to reduce harmful vibrations that can damage your engine's crankshaft, bearings, and rotating assembly. ATI Super Dampers are trusted by professional racers and performance enthusiasts worldwide as a direct upgrade over factory harmonic balancers.

ATI Super Dampers utilize a precision-tuned elastomer ring and machined aluminum housing to absorb and dissipate torsional vibration energy across the RPM range. Unlike stock balancers, ATI's design is SFI-certified and rebuildable, making it a long-term investment in engine longevity and performance.

• Precision-machined billet aluminum construction for strength and reduced rotating mass
