4. Optional upgrade to stainless ARP bolts avail.
5. This is an 8 rib damper. Your OEM belt is 7 rib. Use the first groove closest to engine. Aftermarket belts are 6 rib.
6. Requires a 97.75” long belt - Gates part # K060975.

7. Requires a 97.75” long belt - Gates part # K060975.
8. For 392, use 5.7/6.1 OEM or ARP retaining bolts
9. Adds 3 PSI. Requires grinding the AC bracket for clearance. Use Gates Belt #K100594H (59.4”).
10. NHRA FSS legal as of 7/2/2021. Requires BB Chevy seal and front cover to be bored to fit! 2015+ 354 Super charged Drag Pak - 7.950 drive diameter

1. Used bolt pack #950268 due to timing cover seal clearance.
2. Hubs are dimensioned to clear the stock cast-in timing tab on MOST applications. Due to changes by the manufacturer over time, the tab MAY need to be ground and re-welded. The damper face for pulley mounting will be forward of the OEM location by .150” for 2-ring internal balance, .450” for 3-ring int. balance, .750” for 3-ring ext. balance. Hubs may be shortened by the listed amount for internal balance & by .600” (.150” fwd of OEM) on ext. balance if tab is cleared. 2-ring int. balance can be installed in OEM location with minor clearancing of timing tab & retain OE timing mark.

6. Cannot retain OE location. Must space out accessory pulleys .750”.
8. For 2 ring dampers, use hub 916254M.
9. Supplied with new lightweight aluminum pulley to retain stock belt location.
11. Passenger timing.
12. Not an OEM replacement for stock pulley location.
13. 3/8” pulley bolts in shell. Hub has 5/16” bolts.

1. Locate the correct manufacturer's chart
2. Choose the specific engine application listed down the left side of the chart
3. 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
4. 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.
5. 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.
6. 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.
7. Assembly part numbers that are color coded correspond to the pulley mount bolt pattern listed near the top of the charts.
