ATI Performance Products ATI916178 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916178 Super Damper is a high-performance crankshaft harmonic balancer engineered to reduce torsional crankshaft vibration and protect your engine under demanding racing and street performance conditions. ATI's Super Damper series is trusted by professional racers and performance enthusiasts across drag racing, circle track, road racing, and high-performance street applications.

Unlike OEM rubber-bonded harmonic balancers that can degrade over time and lose their damping effectiveness, the ATI Super Damper uses a precision-tuned elastomer ring housed in a billet aluminum shell. This design provides consistent, reliable damping across a wide RPM range while also reducing rotational mass compared to many factory units.

Key Features:

• Precision-machined billet aluminum construction for strength and reduced weight
• Tuned elastomer damping ring for effective torsional vibration control across a broad RPM range
• SFI 18.1 certified for sanctioned racing competition (verify with current SFI listing for your series)
• Laser-etched or machined timing marks for accurate ignition timing
• Designed as a direct-fit replacement for specific engine applications
• Resists heat, oil, and chemical degradation — will not swell or delaminate like rubber-bonded OEM units
• Compatible with standard timing indicators and front-mount accessories

ATI Performance Products has been a leading manufacturer of performance drivetrain components since 1966. The Super Damper line is manufactured in the USA and is a popular upgrade for any engine build where reliability and precise timing are critical. Always verify fitment using ATI's application guide or the manufacturer's part lookup tool prior to installation.
