[1] These are damper shell
assemblies only - without a hub
[2] These dampers are outer shell, inertia weight and o-rings
only. The inner shell is integral with the crank hub.
[3] Hub is 1” longer than standard.
[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.
[5] Aluminum hubs for these assemblies have a 2.250 seal diameter
with a .500 wall thickness and fits inside the Jessel lower
pulley. This eliminates hub failure at the keyway on engines
driving dry sump pumps and pulleys. For Comp Cams style belt
drive, use a 7", 2 ring Damper due to fitment issues
with the cam timing adjustment. Hub must be machined to fit
inside lower cam gear.
[7] Use hub part # 916172 for 1.245” crankshaft with
BB seal and Chevy bolting.
[8] Timing pointer must be corrected. Original pointer shows
approximately 10° @ TDC (advanced) when the piston is
at TDC.
[13] Use part #916088 for Jesel Belt Drive and steel hub
[15] Non-stock damper - 8 week lead time required.
[16] 7" Dampers will not fit front distributor drive timing covers
[17] Aluminum Hub (part #916099) available. Add $25 at time of order.
|
|
For boat applications, ATI offers Hub Part #916098 to allow the damper to be mounted to the back of the crankshaft.

[1] Requires shorter serpentine
belt. Goodyear pt #4060785 for accessories & 4040405
for AC.
[2] All hubs have 3/16 key @ std SB 10° location.
Please note: 8 groove & 10 groove shell assemblies
are available for supercharger applications. Consult your
ATI salesman. #917017 (7 1/2” diameter, 8 groove,
steel)
#917075 (6 3/4” diameter, 8 groove, aluminum)
[3] Requires shorter belts: Gates #K060775 - 6 rib,
Goodyear #K040405 - 4 rib
[4] Use hub part # 916033A for integral 8mm 28 tooth HTD
pulley.
[5] Contains 40 durometer rubber. Not for full race engines.
Specify 66 rubber or call.
[6] Damper assemblies have all countersunk bolts so nothing
protrudes past front of damper. If you have an older damper
and are ordering a new shell assembly only, you must cut
a .090” x 45° chamfer
on the front of your hub. ATI can also perform this operation
for $40.
[7] Dampers furnished with #916320
hub spacer. For ‘97 & up Camaro/Firebird or
‘96 & up Corvette engine with a reluctor wheel;
discard spacer provided. |
|
[9] Hubs are made of heat-treated alloy steel.
[10] Washer #953070 is required with LT1 hubs and is shipped
with dampers.
[11] Non-removable A/C pulley
- OEM diameter.
[12] Contact Lingenfelter for proper belt set-up.
[13] 2010 LS3 Corvette Grand Sport coupes w/Manual Transmissions
come equipped with a Dry Sump system, so an LS7 style
damper is required.
[14] For no A/C - Order Hub #916349D with pulley delete ring.
[15] Contains 60 durometer elastomers

[1] No supercharger

[2] Damper assemblies have all countersunk bolts so nothing
protrudes past front of damper. If you have an older damper
and are ordering a new shell
assembly only, you must cut a .090” x 45° chamfer
on the front of your hub. ATI can also perform this operation
for $40 if you send your hub in.
[3] CTS-V is 10% UD - Use Duralast Part # 375K4 for AC pulley and Gates Part # K060806, 6 rib for accessory drive.
[4] For applications making over 20 lbs. of boost, ATI offers a stronger, heat-treated & double keyed hub.
Available outright or as a $25 upgrade on new orders - #916032 for 918856.

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.
