Hubs are dimensioned to clear the stock cast-in timing tab. The damper face for pulley mounting will be forward of the OEM location by: .150 for 2-ring internal balance, .450 for 3-ring internal balance, .750 for 3-ring external balance. Hubs may be shortened by the listed amount for internal balance and .600 (.150 fwd of OEM) on external balance if the tab is cleared, or order ATI cover with adjustable tab (part #916259).
2-ring internal balance can be installed in the OEM location with minor clearancing of the timing tab and retain OE timing mark.
