New transmission also plays a factor as well.

Correct, 4 speed to a 5 speed, and and final drive ratio for auto and manual is different vs the pre 2012's. Hence why a lot of people with 2012's and 35's are happy with 4.10's and ect

Yea I understand that. I had a '10 with 37's and 5.13. I can't really compare that to a 14 though which is what the gentleman at Northridge said. Which I why he said go with 5.13 and 40's cause of the new engine/tranny not 5.38

And I believe you can only go to 5.38 if you have a rubicon (44 in front). Just FYI newbi rubi
