ATI Performance Products ATI916578 Super Damper Harmonic Balancer

The ATI Performance Products ATI916578 Super Damper is a high-performance elastomer harmonic balancer (crankshaft damper) engineered to reduce harmful torsional vibration on the crankshaft. Unlike OEM rubber-bonded balancers that degrade over time and lose dampening effectiveness, ATI Super Dampers use a precisely tuned, replaceable elastomer ring captured within a precision-machined billet aluminum shell for consistent, long-lasting protection.

Key Features:

• Precision-machined billet aluminum construction for strength and light weight
• Tuned elastomer dampening ring reduces crankshaft torsional vibration
• Replaceable elastomer insert extends service life and reduces long-term cost
• SFI 18.1 certified for use in sanctioned racing applications
• Multiple timing marks machined directly into the shell for easy ignition timing
• Retains accessory belt drive compatibility
• Direct OEM replacement fit — no modifications required

ATI Super Dampers are trusted by professional racers and performance enthusiasts alike to protect high-revving, high-horsepower engines from the damaging effects of crankshaft harmonics. Whether on the street or strip, the ATI916578 delivers superior vibration control and durability over stock balancers.
