Default Ls7 Crank Timing Gear: Which one?
I'm not sure of the physical difference between the 2006-2008 Ls7 crankshaft gear and the 2009+ Ls7/Ls9 gear. From what I understand, P/N 12581278 is the 06-08, and 12622539 is the 09+ shared on the z06 and zr1. I don't have a PN on mine, and no oil pump yet to check fitment.

Can anyone identify which I have by the pictures?

If you still need it:

Can't really compare them side by side since one is on the motor. But here you go.



LS9 part.



LS-7 part.



Comparison.
