ATI Performance Products ATI916277 Super Damper Harmonic Balancer

The ATI Performance Products ATI916277 Super Damper is a high-performance torsional harmonic damper engineered to reduce crankshaft torsional vibration in demanding performance and racing applications. ATI Super Dampers are among the most trusted harmonic balancers in the industry, combining precision engineering with SFI certification for use in sanctioned racing events.

Unlike OEM rubber-bonded balancers that degrade over time and lose damping effectiveness, the ATI Super Damper uses a precision-machined elastomer ring bonded between inner and outer steel rings to provide consistent, long-lasting torsional damping. This design protects the crankshaft, bearings, and rotating assembly from harmful harmonic vibration at high RPM.

Key Features:

• SFI 18.1 certified for use in sanctioned drag racing and performance applications
• Precision-machined billet steel construction for strength and durability
• Replaceable elastomer damping ring for long service life
• Reduces crankshaft torsional vibration to protect engine components
• Laser-engraved timing marks for accurate ignition timing
• Direct OEM replacement fit for easy installation
• Manufactured in the USA by ATI Performance Products

ATI Super Dampers are the preferred choice of professional engine builders and racers worldwide. Whether used on the street or strip, the ATI916277 delivers proven protection and performance for your engine's rotating assembly.
