ATI Performance Products ATI916020 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916020 Super Damper is a high-performance crankshaft harmonic balancer engineered to reduce torsional vibration and protect your engine's rotating assembly. ATI's Super Damper line is trusted by professional racers and performance enthusiasts worldwide for its superior vibration dampening capability and durability under extreme conditions.

Unlike OEM rubber-bonded balancers that degrade over time and lose effectiveness, the ATI Super Damper uses a precision-tuned elastomer ring design that maintains consistent dampening performance throughout its service life. This helps protect crankshafts, bearings, and other drivetrain components from the harmful effects of harmonic vibration at high RPM.

Key Features:

• Precision SFI-certified construction for sanctioned racing applications
• Superior torsional vibration dampening compared to OEM-style balancers
• Durable billet aluminum outer shell with elastomer dampening ring
• Maintains performance over time — does not degrade like rubber-bonded OEM units
• Precision laser-etched timing marks for accurate ignition timing
• Manufactured in the USA by ATI Performance Products

ATI Performance Products has been a leading manufacturer of performance drivetrain components since 1966. The Super Damper is a direct upgrade over factory harmonic balancers for performance street, strip, and race applications where engine protection and precision are critical.
