Super Damper Harmonic Dampers
ATI's Super Damper for the Mini Cooper standard and "S" model is a direct replacement for the stock OEM damper from 2001 through 2006. The heart of this unit features ATI's "damper within a damper" design that has put ATI ahead of the rest. The outer shell retains the OEM 6-rib serpentine belt locations and includes laser-etched timing marks.
Features
- 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
- Laser engraved 360° timing marks
- Use With Dry Sump Counter Bore Accepts Drive Mandrel
- Note: 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.
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).
