  • Black zinc chromate finished
  • Tunable, rebuildable, and extremely efficient at ALL RPM

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).

Installation Note: ATI dampers are a 1-thousandths press fit, they do not just slide on like OEM crank pulley. They will need to be pressed onto the crank snout with a damper install kit.
