ATI Performance Products ATI918066 Super Damper Harmonic Balancer

The ATI Performance Products ATI918066 Super Damper is a high-performance harmonic balancer engineered exclusively for high-RPM performance and racing engines. Built by one of the most respected names in driveline technology, ATI Super Dampers are the gold standard for crankshaft vibration damping in both street performance and all-out competition applications.

ATI's patented Super Damper design uses precision O-rings retained in computer-machined grooves within a steel inertia weight to absorb and dissipate destructive crankshaft torsional vibrations. Unlike rubber-bonded OEM balancers that can fail under sustained high-RPM use, the Super Damper's O-ring design remains stable and effective across a wide range of temperatures and power levels.

Key Features:

• Patented ATI Super Damper design developed exclusively for high-performance engines
• Steel inertia weight with computer-machined O-ring grooves for precise harmonic damping
• Exceeds SFI 18.1 specification requirements for competition use
• Computer-controlled, laser-engraved 360-degree timing marks for accurate ignition timing
• Black zinc chromate finish for corrosion resistance and durability
• Serpentine belt groove(s) machined directly into the outer damper shell
• Compatible with ATI GM-front crank hubs for maximum application flexibility
• Manufactured in-house at ATI's Baltimore, Maryland facility with full quality control

ATI Super Dampers have been proven in Winston Cup competition over two million cycles and in drag racing engines for over a decade. Whether building a dedicated race car or a high-powered street machine, the ATI918066 Super Damper delivers the reliable crankshaft protection and timing accuracy your engine demands.
