ok here's another option for 3.5" lift it worked out good for me sofar go buy a set of 3.5 lift coils for the front of your jeep and put the front coils in the back they'll bolt directly in giving you a 3.5" for about the same price as the coil spacers rides a little harder in the rear but very livable but 3.55's and 33's will suck i'm running 31's and i can't stand it i need 4.11's bad
