If you plan on taking it off road in the future, do it right the first time and go with a suspension lift. AEV makes a good 2.5" so I hear. I have the 2.5" Teraflex with Bilstein 5100 shocks, and couldn't be happier with this setup.

Do not perform any mod for looks alone, mod for function. I promise you if you plan your mods to improve function, you will have a Jeep that "looks" the way you want.
