Thanks for those links. When I said 'higher' I meant numerically. In my previous jeep I went from 3.09s to 3.71s to accommodate the 31-10.50s, and while that wasn't enough, it did the trick, and it was cheaper than changing out the diffs themselves. The 4.1 diff gearsets I have in this seem to be about the same with these 32" tyres. I should have gone to ratios in the mid-4s methinks...

What I really need with THIS vehicle is a closer 5th gear - it's too far apart from 4th. Either that or a lower overall drive ratio (cheaper). I'll look into that transfer case.

If you put higher ratio diffs in,both of course..say 3.71:1..you would be in second gear in a head wind...that would really suck..
But your overall gas mileage would improve..mucho..
The old flat head Fords..'49-'54..had 4.11:1 rear ends.. they were the ideal ratio for making the old girls "Peel"to impress the chicks at school..no top end..but fast enough to scare a fellow..That is why they came out with overdrive.


You may want to look at your transfer case instead.This would be your best bet...change the input gears..

There are 40 something gear variations in the transfer cases..so there is something there for you..
Changing your diffs would not be the answer..
