STD FRONT - USE WITH DRY SUMP COUNTER BORE TO ACCEPT DRIVE MANDREL - 2ND 1/4" KEYWAY AT 180° FROM STANDARD [4]

[4] Hubs for these assemblies have a 2.280 counterbore. A standard length crank bolt is used and the mandrel bolts to the 3 pulley mounting holes. This eliminates the 4” - 6” long bolt that is ineffective in retaining torque. Adapter part # 916321 is available for existing mandrels with 1.245” pilot.

Super Damper® Harmonic Dampers


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
  • OEM equipment on ZZ572 GM Crate Engines
  • Tunable, rebuildable, and extremely efficient at ALL RPM

Inner and outer shells are available in aluminium 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).
