ATI Performance Products ATI918007 Super Damper Harmonic Balancer

The ATI Performance Products ATI918007 Super Damper is a high-performance harmonic balancer engineered for demanding race and street applications. ATI's patented Super Damper design is the only crankshaft damper developed exclusively for high-RPM performance engines, offering superior vibration damping where OEM rubber-bonded balancers fall short.

Unlike conventional harmonic balancers that rely on a bonded rubber ring, the ATI Super Damper uses precision-machined elastomer O-rings seated in computer-machined grooves within a steel inertia weight. This proven design effectively cancels torsional crankshaft harmonics across the full RPM range, protecting bearings, reducing wear, and freeing up power that would otherwise be lost to vibration.

Key Features:

• Patented ATI Super Damper design with elastomer O-ring technology — not bonded rubber
• Steel inertia weight with computer-machined grooves for precise O-ring retention
• Black zinc chromate finish for corrosion resistance
• Computer-controlled, laser-engraved 360-degree timing marks for accurate ignition timing
• SFI 18.1 certified for NHRA and IHRA sanctioned competition
• Developed and tested in professional motorsports competition
• Manufactured in the USA by ATI Performance Products

The ATI918007 Super Damper is built to exceed SFI 18.1 specifications and is a direct upgrade over factory harmonic balancers for performance-built engines. It is sold individually.
