ATI Performance Products ATI917080 Super Damper Harmonic Balancer SBC - 7.074

The ATI Performance Products ATI917080 Super Damper is a high-performance harmonic balancer specifically engineered for Small Block Chevy 400 cubic inch engines requiring external balance (26 oz. imbalance). This patented crankshaft damper is designed exclusively for high-performance and racing applications, delivering superior torsional vibration control compared to OEM-style balancers.

Key Features:

• 7.074-inch outer diameter steel construction with black zinc chromate finish
• 3-ring elastomer design with eight computer-machined grooves for optimal vibration dampening
• Steel outer shell, inner shell, and inertia weight for maximum durability
• SFI 18.1 certified for racing applications
• Laser-engraved 360-degree timing marks for precise engine tuning
• External balance configuration for SBC 400 engines (26 oz. imbalance)
• Single keyway design compatible with standard Chevy bolt pattern pulleys
• 1.800-inch width for proper crankshaft engagement

Testing has proven the ATI Super Damper to be 30% more effective than original equipment dampers at 6,000 RPM, reducing torsional vibrations that rob horsepower and damage engine components. The elastomer construction absorbs harmful crankshaft harmonics while stabilizing camshaft and ignition timing, resulting in improved engine durability and performance. Whether for street performance or competition racing, this Super Damper represents the gold standard in harmonic balancer technology. Mounting hardware sold separately.
