Default are all ls crank sprockets the same length?

I need to know if the ls1 vette and lq9 truck sprockets are the same length, before I press it back on the crank. Thanks

No they are different. The truck sprocket is offset further than the vette. There are 3 different offsets.

Truck - Furthest
F-Body/GTO - Middle
Vette/CTS-V - Closest

I believe you are confused...the accessories and crank PULLEY are as you describe, the crank timing chain sprockets are the same to my knowledge.

Exactly what i was looking for. I know the crank pulleys all have different offsets, but I was concerned about the timing chain crank gear/ oil pump gear. I measured off of another motor and it was within .02, so i am assuming I am good.

The timing gear/sprocket is the same on all wet sump ls motors. Both the LS1 and LQ9 are the same.
