Default 8spd gears?
I love my 2016 6.2 8spd but after my headers install it feels a little sluggy down low. Anyone done gears on these yet? What GM gears can I go to. Any 3.73s out there?

I think the rearend is still a 14 bolt on the 6.2 trucks. The 5.3/4.3 have the new 12 bolt.

14 and up have new 12 bolts....6.2's have the 12 bolt 9.76 R&P and 3.73's are available for those. The 5.3's have the 12 bolt 9.5 R&P. 3.73's would be damn near perfect.
