ATI Performance Products ATI918564 Super Damper Harmonic Balancer for Toyota 2ZZ-GE

The ATI Performance Products ATI918564 Super Damper is a high-performance harmonic balancer engineered specifically for Toyota 2ZZ-GE 1.8L engines found in Celica GT-S, Lotus Elise, and Lotus Exige applications. This precision-engineered damper provides superior protection against destructive torsional crankshaft vibrations at all RPM levels, addressing a critical weakness of factory dampers and non-dampened pulleys in high-performance applications.

Key Features:

• 5.670-inch outside diameter aluminum construction with elastomer dampening
• 6-groove serpentine pulley design with 4% overdrive for improved accessory performance
• 3-ring elastomer design for superior vibration dampening across the RPM range
• SFI 18.1 certified for racing and competition use
• Laser-etched 360-degree timing marks for precision tuning
• Black zinc chromate finish for corrosion resistance
• Single keyway design for secure installation
• Internally balanced configuration

This Super Damper replaces the inadequate factory harmonic balancer with a proven racing-derived design that protects your engine's crankshaft and bearings from harmful vibrations. The elastomer construction effectively absorbs torsional vibrations while maintaining OEM serpentine belt compatibility. Mounting hardware sold separately. Weighs 3.60 lbs.
