ATI Performance Products ATI917046 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI917046 Super Damper is a precision-engineered torsional vibration damper (harmonic balancer) designed for high-performance and racing engine applications. ATI Super Dampers replace the factory harmonic balancer with a unit built to withstand the increased stress of modified, high-revving engines while effectively controlling crankshaft torsional vibration.

Unlike standard OEM balancers that can deteriorate under sustained high-RPM use, ATI Super Dampers use a multi-piece, bonded elastomer or fluid-damping design that maintains consistent damping performance across a wide RPM range — protecting your crankshaft, bearings, and rotating assembly from destructive harmonic vibration.

Key Features:

• SFI 18.1 certified for sanctioned racing use
• Precision CNC-machined billet aluminum construction
• Replaceable elastomer inertia ring for extended service life
• Laser-engraved timing marks for accurate degree readings
• Protects crankshaft and rotating assembly from torsional vibration damage
• Direct bolt-on replacement for OEM harmonic balancer
• Designed for high-performance street, strip, and race applications

ATI Performance Products has been a trusted name in professional motorsports for decades, supplying dampers and transmission components to top-tier drag racing, road racing, and oval track teams. The ATI917046 Super Damper delivers that same race-proven engineering in a package suitable for serious performance builds.
