So after a week of driving with my new gears here's some things I noticed.
I went from 4:10 to 4:88's for my new 33's.
I havent gone offroading yet, but I can tell that at take off if I barely release the clutch it starts moving. Before I had to give it a little gas. So I can bet it will help out alot when offroading.
Freeway driving has been good also. Sometimes it kinda bogs down in 5th around 70mph and other times it rolls at 85mph. Gas mileage has suffererd a bit.
I used to shift around 3000rpm's and 4000rpm's when climbing hills, now I have noticed that when the Jeep tells me to shift at 2100rpm's I can and it doesnt bogg down like before. So maybe I can save gas by listening to the Jeep?
Overall I'm pleased with the gear swap and I am hoping to go offroading new years weekend to really test them out.

Gas mileage should only change if you drive at the higher RPM's instead of shifting for optimum mileage (2000RPM-ish) Since you're geared a lot lower the engine shouldn't need the extra RPM's for hills and such. You're going to have to relearn how to drive it. Offroad, you might not notice the gears as much unless you like to idle up obstacles. This is really where lower gears shine. It should bog down as much when you're trying to use minimal throttle input.

Gearing doesn't help mileage much, just makes it a heck of a lot more drivable and a lot easier to crawl over rocks, far less abuse on the clutch

please dont take this noob question as a thread jack but i too plan to increase in tires size this year..is regearing possible/worth it on an auto tranny?

Yes as the engine still has to deal with the gear ratios being off.

I love my 4.88's
would have went bigger but would have needed axles to do it.

Cant wait to do this...hope the tax man is good to me this year

I just regeared to 4:88's also and Jeffy is right about having to relearn how to drive it, on the trail, when in 4 low and first, first is really low, I like it... :biggrin:

I think he meant the computer needs to relearn a little to. thats the way I took it but that way to cause it's is that drastic of a improvement!! woot 4.88's+

Gearing doesn't help mileage much
Gearing should help mileage as it is placing the engine back into the optimal powerband instead of lugging the engine trying to get the oversized tires moving. Some may say it hurts mileage but my guess would be they can't keep their foot out of it after a regear because the jeep is so much more fun to drive.
I run 5.38 gears with 35" and 36" tires and get respectable fuel mileage, around 15city and 17hwy, so you can't tell me gearing hurts mileage.
