I have a 2011 unlimited rubicon, auto with 37s, 4.10 rear and a RIPP supercharger. It struggles a little in a headwind and climbing hills, but will run in overdrive at highway speeds. If I need to or if it is changing in/out of overdrive, I just turn off the overdrive. Not the perfect setup,but definitely tolerable till I re-gear.

Its livable but you mpg (which you own a jeep so who gives a s%$) will go down and it will take you a little longer to get up to speed. but it can be done

Im running a 2011 auto with 3.73 on 37s but I live in a flat area and when I go off roads its just deep mud so not regearing has yet to bother me. Oh I also average about 15mpg with mixed driving.

I have an auto with 37s running 5:13s and it is a dog... Can't imagine what stock gears would be like

I have a diablosport programmer and gearing is not bad at all on the highway. I have not regeared.
