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
OEM equipment on 392 Mopar Crate Engines
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).
[1]
Not an OEM replacement - damper/hub are not serpentine.
Can add a serpentine 6.750 / 7.50 for accessories with
hub part #916060.
[2] All Pulleys are in OEM
locations. Power steering pulley is 15% underdrive, alternator
and water pump are 5% underdrive. A 10mm shorter belt
is required for power steering pulley. Damper shell and
pulley are aluminum with steel hub. Be sure to check your
crankshaft for roundness. If it is equal to or more than
.001" out of round, you will need to adjust for proper
damper press fit.
[3]
Part number designates shell only consisting of outer
shell and installed inertia weight, without power steering
pulley. For power steering pulleys, order part number
916738 for R32, or part 916737
for R33 & R34.
[4] Damper includes new aluminum
water pump pulley for clearance. A/C belt is a 25% overdrive
- DO NOT USE BELT IF RACING! 3% underdrive on power steering,
OEM size on water pump. [5] If installing on a standard “DE”
engine, use ATI crank spacer #916298 behind the damper.
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.
