if you dont plan on wheeling it and just want a different look, get some fancy rims and put 31" A/T tires on it, im pretty certain 31's will fit with the proper rim with no lift. they may rub a little. if you dont care then great, if you dont want any rubbing then a 2" spacer will work fine. a good quality coil lift is what most will recommend but if its just a looks thing and not the performance thing then spacers would do the trick. keeping it closer to stock height avoids the stering issues and driveline vibration issues.
now samm, i have a question that i've always wanted to ask. and im not being a dick when i ask this. but why own and drive a jeep if you dont plan on fourwheeling?
personally i love jeeps, they wheel awesome and i drive the crap out of mine. but as an every day driver i can think of many other vehicles that are way more fun on the street.
