I just looked, my window sticker is 3.21..im sorry not sure what this means..is this/or does this mean these are weaker gears, am I kind of lagging with these..are the helping me currently to get the 21+ mpg Im getting..is 3.21 the worst or weakest ever or of all..argggh.being an newb. 
Any hill at all? Useless 6th gear, sucks fuel and can't maintain any sort of speed. I only use 6th gear on level ground or down hills for MPG reasons.
Is it drivable? yeah.
Is it frustrating? more times than not.
On the bright side, I drive like a grandma and even with 35s in a 2 door, I average 17.5 minimum, usually closer to 18 mpg. (no muffler which I hear helps)

I just picked up a 2014 JKU Sport..Doing my homework..I'm not even sure what my gears are stock, anyone know?? Im getting 21+ mpg now..want 35's on 2.5 of lift..thinking I'll drop down to 16-17 mpg..sound about right?? Do the JKU 14's with the newer engine need the regear for just 35's?
Regarding the 2014, I have a 2014, went with 34" duratracs ($1500), Rough Country 2.5" spacer lift ($180), AEV Geo Correction Brackets ($100)...lack of power is really not an issue at all...the geo brackets helped...3.21 gears, not even considering re-gearing...~16 mpg...also, this is my DD, only get off road a few weekends a year.

I've got 33s. Do I wish I had 35s? Absolutely. Am I glad I went with 33s? Absolutely. A few things were the deciding factor for me.
33s are much simpler. Basically just bolt them on and go. Fit the stock tire carrier, not even the slightest concern with re gearing (3.21), still gets decent MPG, and my Jeep goes off road maybe twice a year.

Not hyjacking the thread, I'm just curious If you're still on the stock axles with your 37s? That's my next move and I'm debating waiting until several years while I save for Dynatrac 60s, or if some chromoly shafts and guessets would suffice on the front D30.
