ATI Performance Products ATI916563 Super Damper Supercharged Series Harmonic Balancer

The ATI Performance Products ATI916563 is a Super Damper Supercharged Series harmonic balancer engineered for high-performance and racing engines running supercharger drive systems. This unit integrates ATI's proven Super Damper technology directly into the crankshaft blower pulley, eliminating the need for a separate crank-mounted blower pulley and reducing overall drivetrain complexity.

Key Features:

• Supercharger-Ready Design: Features external belt drives compatible with virtually any type of blower belt, placing damper protection inside the crankshaft blower pulley
• SFI Certified: Exceeds SFI 18.1 specifications for sanctioned racing applications
• Laser-Engraved Timing Marks: Full 360-degree timing marks for precise engine tuning
• Black Zinc Chromate Finish: Durable corrosion-resistant finish for long service life
• Eliminates Torsional Vibration: Patented elastomer design effectively dampens crankshaft harmonics at all RPM ranges
• Tunable and Rebuildable: O-rings can be replaced to restore the unit to new specifications, extending service life
• Dual-Keyway Hub: Provides secure crankshaft indexing for high-power applications
• Reduces Crankshaft Bending Moment: Optimized pulley offset keeps the blower drive close to the engine block

ATI Super Dampers are the damper of choice in NASCAR and professional drag racing, with O-ring life tested to over 3 million cycles in competition. The ATI916563 is built to the same exacting standards, making it equally at home on street-driven supercharged vehicles and all-out race builds.
