The patented ATI Super Damper is the only damper designed
exclusively for high performance 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
contain the steel inertia weight. The 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).

How
to read this chart |
 |
- Locate the correct manufacturer's chart
- Choose the specific engine application
listed down the left side of the chart
- Determine if the damper needs to be internally
or externally balanced ( external balance dampers are constructed
of steel only). Black bars that extend horizontally across
the entire chart designate these sections
- Determine if you need steel or aluminum
shells. Labels for this information are listed across the
top of the chart in columns 2 and 3.
- Once you have determined the shell material,
you need to find the outside diameter (OD) of the desired
steel or aluminum shell. Then choose between 2 or 3 rings
and the desired weight of the damper.
- From the far right section of the chart,
select either a steel or aluminum hub for your desired engine
application. To determine the correct damper assembly part
number that intersects is the correct damper assembly.
- Assembly part numbers that are color
coded correspond to the pulley mount bolt pattern listed
near the top of the charts.
