I have the 4.2 lifted with 33's on it. I want to put new gears and would like to see what others are running. It still has the stock axles. I was thinking of going 4.88. I use it as a DD but only travel 25 miles round trip to work. I do weekend wheeling when I can.

4.88 on 33's is low 4.10 would be better choice if you are going to keep 33's. Google gear ratio calculator and crunch the numbers.

I got one of those calculators, and 4.88 and 33" tires gives you this:
gear MPH RPM
1st 3.83 14 2664
2nd 2.33 23 2662
3rd 1.44 36 2575
4th 1 60 2981
5th 0.79 70 2747

assuming ax15 manual transmission

So depending on what you want the jeep to do, its quite low.
