ATI Performance Products ATI918572 Super Damper Harmonic Balancer - 7.07 6-Groove

The ATI Performance Products Super Damper harmonic balancer is engineered specifically for 1994-1998 Toyota Supra JZA80 models with 2JZ-GTE engines. This high-performance damper effectively eliminates torsional crankshaft vibrations that can damage engine components, making it ideal for both street performance and competition applications.

Key Features:

• 7.07-inch outside diameter sized for OEM belt compatibility
• 6-groove serpentine belt design with 6.78-inch aluminum shell
• SFI 18.1 certified for NHRA and IHRA competition use
• Laser-engraved 360-degree timing marks for precision tuning
• Steel inertia weight with computer-machined O-ring grooves
• 2-ring design with dyno-tested durometer O-rings
• Black zinc chromate finish for corrosion resistance
• Tunable and rebuildable for long-term performance

ATI's patented Super Damper design uses precisely calibrated O-rings retained in machined grooves to absorb harmful torsional vibrations across the entire RPM range. Unlike traditional elastomer-style dampers that deteriorate over time, the Super Damper maintains consistent performance and can be rebuilt when needed. The laser-engraved timing marks provide accurate degree markings for advanced tuning applications.

This damper is designed for use with OEM-size drive belts and is sold individually without mounting hardware. Exceeds SFI 18.1 specifications and is trusted as OEM equipment on various high-performance crate engines.
