You have stock 3.73's.

Do you ever plan on going bigger than 33's? If not, then 4.56 should be where you want to be.

Mileage improvement will be marginal, but you will get your powerband back.

You need to change your front along with the rear.

If you ever go 35s definitely go with the 4.88s. It's what I'll be doing with my current 33s until they wear down and I can move up to 35s.

is it an auto or a 5 speed? because correct me if im wrong. Some people say that 4.56 would be better with the auto because 4.88's are too high for the three speed and u'd be running up your RPM. But if your a Stick then 4.88 would be better if u plan on going for 35's

He has a 2004, which would be the 4-speed auto trans.

Manual or 4-spd auto, 4.56 is the recommended ratio for 33's. The 4-spd needs lower gearing than the old 3spd because of the overdrive.

Its an auto. The only problem i have is overdrive...when it kicks in at freeway speeds, it almost feels as if the jeep is about to start going backwards. Is there any way to fix this, without a regear?

you mean it bogs?. in that case a re gear would be the best thing to do unless u want a supercharger... you could do the little power add ons like intake,spacer,chip and blah blah blah but to get more power but regearing in the long run will make u a happier camper

Supercharger would be a lot more but you should still regear first. A supercharger is not the way to correct for an incorrect/too high of a gear ratio.

When you have a choice, buy American.

Do the re-gear! For 33's and the 4-speed auto you want to go with 4.88's. The overdrive on the 4-speed auto is 0.69, so the lower (higher numerically) gear is warranted. If you ever go 35's it will still work but won't be optimal, 5.13's would be better. The D30 is the limiter here; it will only go to 4.88.
