ATI Performance Products ATI916177 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916177 Super Damper is a precision-engineered torsional crankshaft damper designed for high-performance and racing applications. ATI Super Dampers are SFI 18.1 certified and built to withstand the extreme RPM and power demands of modified engines where stock harmonic balancers fall short.

Unlike OEM rubber-bonded dampers that degrade over time and fail under high-RPM stress, ATI Super Dampers utilize a precision-machined aluminum shell with a captured, elastomer-tuned inertia ring. This design effectively absorbs and dissipates crankshaft torsional vibrations, protecting your engine's crankshaft, bearings, and rotating assembly from damaging harmonics.

Key Features:

• SFI 18.1 certified for sanctioned racing competition
• Precision-machined billet aluminum construction
• Tuned elastomer inertia ring for effective vibration damping
• Replaces worn or inadequate OEM harmonic balancers
• Designed for high-RPM performance and racing environments
• Includes timing marks for accurate ignition timing reference
• Rebuildable and re-tunable design for long service life

ATI Performance Products has been a trusted name in motorsports since 1966, supplying dampers and torque converters to professional racing teams across drag racing, road racing, and oval track disciplines. The ATI916177 Super Damper is an ideal upgrade for any serious performance build requiring proven crankshaft protection.
