ATI Performance Products ATI916249 Super Damper Harmonic Balancer

The ATI Performance Products ATI916249 Super Damper is a high-performance harmonic balancer engineered to eliminate torsional crankshaft vibration in performance and racing applications. Designed and manufactured by ATI Performance Products at their facility outside Baltimore, Maryland, this damper is built to exceed SFI 18.1 safety specifications, making it suitable for both street and sanctioned racing use.

ATI's patented Super Damper design uses precision-machined inner and outer shells paired with a steel inertia weight. The inertia weight features computer-machined grooves that retain properly durometer-rated O-rings, which are dyno tested for each specific application to ensure optimal vibration damping across the entire RPM range.

Key Features:

• Eliminates harmful torsional crankshaft vibrations
• Exceeds SFI 18.1 specification
• Laser-engraved 360-degree timing marks for precise ignition timing
• Tunable and rebuildable design for long service life
• Black zinc chromate finish for corrosion resistance
• Available in aluminum or steel shell construction with steel inertia weight
