ATI Super Damper Dry Sump GM LS3/LS7/LS9 Harmonic Balancer 6 & 4 Rib 918639

*with LS3 ACCESSORY DRIVES

The patented ATI Super Damper is the only crankshaft damper designed exclusively for high performance Chevy engines.

  • Eliminates torsional crankshaft vibrations
  • Exceeds SFI 18.1 specs
  • Black zinc chromate finished
  • Tunable, rebuildable, and extremely efficient at ALL RPM
  • Laser engraved 360° timing marks

Inner and outer shells are available in aluminum or steel, and contain a steel inertia weight. This inertia weight has six (2-ring design) or eight (3-ring design) computer machined grooves to retain the proper durometer O-rings (dyno tested for each application). The dampers come with six outer grooves for standard OEM drive systems—but eight and 10 grooves are available for supercharger or turbo applications.
