Ok well I pulled the trigger. I was back and forth between 4.88 and 5.13. with only 150 rpm different. I went for the 5.13. I do plan on getting 35s as soon as my 33 are no good. Or if I can find some one who wants 33 for 35. I know Im wishing. Any way I am very excited. Let you know what I think when they get installed.

 

+1... I'd get the 35s ASAP personally...

At 70MPH with 35s and 5.13 my auto turns 2450-2500 RPM in OD. Obviously you get up to 2600-2700-2800 if you push 75-80 ever (not that you will be able to do so easily in a lifted 4-door JK with 35s LOL). I don't think I've hit 80 yet since the gears...

However, with 33s it's going to be noticably higher yet...

And higher yet if you have a manual tranny, as the 6th speed OD is not as much of a drop as the auto 4th. I think I read 5.13 and 35s on a 6 speed you will be closer to 2800 in 6th at 70 mph... add to that with 33s.

 

yeah when I looked at the chart it was 150 to 200 rpm difference. But yes I am looking to get 35'' ASAP

 

You will be very happy with the 5.13's. Congrats
