Mine came with 3.73s from the factory so that's got to be available.

that is the GM upgraded drive shaft....in reference to shaft speed mentioned....it is rated upto that rpm.

just showing you what GM says, the 4.10 swap (if doable), may exceed that rpm

Alright guys update. I've basically just given up on the idea for now. I'm hopefully buying a custom tune for my truck soon or wake it up.
