ATI Performance Products ATI916270 Super Damper Harmonic Balancer

The ATI Performance Products ATI916270 Super Damper is a high-performance harmonic balancer engineered to eliminate destructive torsional crankshaft vibrations in high-RPM performance and racing engines. Developed and refined through decades of motorsport competition, ATI's patented Super Damper design outperforms OEM rubber-bonded balancers and is the choice of professional racers and serious enthusiasts alike.

Key Features:

• Patented ATI Super Damper technology designed exclusively for high-performance engines
• Exceeds SFI 18.1 certification requirements for NHRA and IHRA sanctioned competition
• Steel inertia weight with computer-machined grooves retains precision-durometer elastomer O-rings for consistent harmonic dampening
• Aluminum and/or steel inner and outer shell construction for strength and reduced rotating mass
• Black zinc chromate finish for corrosion resistance and a clean appearance
• Computer-controlled, laser-engraved 360° timing marks for accurate ignition timing
• Proven in millions of competition cycles in drag racing and oval track applications

Unlike OEM dampers that rely on a bonded rubber ring that degrades with age, heat, and exposure to solvents, the ATI Super Damper uses multiple precision elastomer O-rings contained within machined grooves. This design maintains consistent dampening characteristics throughout the life of the component and can be rebuilt or retuned as needed. The ATI916270 is manufactured in the USA at ATI's facility in Gwynn Oak, Maryland.
