Newbie here....two weeks ago I purchased a 06 Rubicon and I'm looking to put a lift on it soon. I don't go off road all the time, so I'm not trying to build a rockcrawler or anything crazy. I do want good capabilities though. I plan to join a club in No. Virginia/DC area when I get back from Afghanistan in June. I'm going to get a lift to fit 33's. I'm curious to see how hard it would be to move up to 35's down the road, after having a 3 or 4 inch lift. If I get a 4" would I only have to put in 2" spacers? 3" lift and add 2" spacers and 1" Bl? What other mods would have to be done to the jeep? Would I have to get longer drivelines, or anything else? Appreciate your time...
