ATI Performance Products ATI918311 Super Damper Harmonic Balancer

The ATI Performance Products ATI918311 Super Damper is a high-performance harmonic balancer engineered to eliminate torsional crankshaft vibrations in demanding racing and high-RPM applications. This patented Super Damper represents ATI's decades of experience in drag racing and performance engine development.

Key Features:

• Designed exclusively for high-performance engines operating at 6000+ RPM
• Exceeds SFI 18.1 specifications for competition use
• Features elastomer design with steel inertia weight in aluminum or steel shells
• Eight computer-machined grooves retain proper durometer O-rings dyno-tested for optimal performance
• Black zinc chromate finish with laser-engraved 360-degree timing marks
• Tunable and rebuildable design for extended service life
• Proven through millions of cycles in NASCAR and drag racing competition

ATI Super Dampers utilize an unbonded elastomer design that functions as two dampers in one, providing superior vibration control compared to conventional single-strip dampers. The replaceable O-ring system ensures consistent performance and allows for rebuilding to factory specifications. This damper is extremely efficient at all RPM ranges and can improve engine performance while protecting critical crankshaft components from destructive harmonic vibrations.
