ATI Performance Products ATI917412 Super Damper Standard Harmonic Balancer

The ATI Performance Products ATI917412 Super Damper is a patented, high-performance harmonic balancer engineered exclusively for demanding race and street applications. Designed to eliminate destructive torsional crankshaft vibrations that rob power and accelerate engine wear, this Super Damper is a direct upgrade over factory OEM dampers and non-dampened pulleys that provide little to no protection at high RPM.

Key Features:

• Patented Super Damper design engineered exclusively for high-performance engines
• Inner and outer shells constructed from aluminum or steel with a steel inertia weight
• Tunable, rebuildable construction for long-term serviceability
• Laser-engraved 360-degree timing marks for precise ignition timing
• Exceeds SFI 18.1 specifications — accepted for NHRA and IHRA sanctioned competition
• Black zinc chromate finish for corrosion resistance and durability
• Extremely efficient vibration damping at all RPM ranges

The ATI Super Damper effectively controls crankshaft harmonics across the entire RPM band, helping protect rotating assembly components while freeing up measurable horsepower and torque. Built and tested at ATI's manufacturing facility outside Baltimore, Maryland, every Super Damper undergoes rigorous quality control to meet the demands of professional racing and high-performance street use.
