Getting back to gears....
I broke a few rear ring gears on my old 44 with 5.38 gears. If I was building a 44 again I would do 5.13 gears.
...this is where I am currently headed. I have been told that the 5.13 is weaker than a 4.88 and that I may be giving up some passing gear, but it will be better on my JKU with my 3.6 than the 4.88
I have been heavy on the skinny in the past due to not having lockers. I hope that with lockers I will not have to get into it because I hear the 5.13 does not like a heavy foot. I am not sure what other advantages the 4.88 has other than being a little beefier. RPM wise they seem about the same.
End game is 37's although I will be on my 35's for at least another 10-15k miles or more, these Nitto Trail Grapplers are awesome.
