ATI Performance Products ATI916214 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916214 Super Damper is a high-performance crankshaft harmonic balancer engineered to reduce torsional vibration and protect your engine's crankshaft, bearings, and valvetrain from damaging harmonic resonance. ATI's Super Dampers are a trusted choice in professional racing and high-performance street applications where stock balancers fall short under increased RPM and power levels.

Unlike factory rubber-bonded harmonic balancers that degrade over time and lose effectiveness, the ATI Super Damper uses a precision-machined billet aluminum housing with an elastomer ring specifically tuned to the application. This design provides consistent, reliable dampening across a wide RPM range and holds up to the rigors of sustained high-performance use.

Key Features:

• Precision billet aluminum construction for strength and reduced rotational mass
• Tuned elastomer dampening ring for superior torsional vibration control
• SFI 18.1 certified for sanctioned racing use
• Replaces worn or inadequate OEM harmonic balancers
• Designed for high-RPM and high-horsepower applications
• Timing marks machined directly into the balancer for accurate ignition timing
• Corrosion-resistant finish for long service life

The ATI Super Damper is a direct upgrade for performance builds where engine longevity and reliability are critical. It is SFI-certified, making it eligible for use in many sanctioned racing events. Always verify fitment by cross-referencing your engine's specifications with ATI's application guide.
