ATI Performance Products ATI916785 Super Damper Harmonic Balancer

The ATI Performance Products ATI916785 Super Damper is a high-performance harmonic balancer (crankshaft damper) engineered to eliminate destructive torsional vibration at the crankshaft. Designed for high-performance and racing applications, the ATI Super Damper protects engine internals while freeing up power that stock or worn OEM dampers leave on the table.

Key Features:

• SFI 18.1 Certified — meets or exceeds SFI specifications for sanctioned NHRA and IHRA racing competition
• Precision Aluminum Construction — lightweight, durable billet aluminum shell with black zinc chromate finish for corrosion resistance
• Elastomeric Damping Ring — computer-matched inertia weight and elastomer ring tuned to cancel crankshaft torsional harmonics across the RPM range
• Laser-Engraved 360° Timing Marks — full-circle degree markings allow precise engine timing and tuning
• Serpentine Belt Compatible — designed for OEM-style serpentine belt drive systems
• Drop-In Fitment — direct replacement installation, no modification required

ATI Super Dampers are developed and validated on the dragstrip before reaching street and race applications. By reducing crankshaft harmonics, the ATI916785 helps improve throttle response, extend engine life, and deliver more consistent power output. Also commonly referred to as a harmonic balancer, crank damper, or crankshaft pulley damper.
