have you bothered to do a searc mate, there are thousands of threads related to what your after
the RE 3.5" kit is a good kit but dont forget your gonna need shocks to go with it and if your running 3.5"s of lift with stock 29" wheels its gonna look stupid especially if your runnin 7" flares to cover the 35's
from what iv been told the best combo for 35's is a 4" lift.....or the 4.5" lift RE kit
im currently running 3.5"s with flat flares and i recon i could fit 35's under mine fine with some bumpstops
heaps of members have the RE 3.5 or 4.5 kit and are happy with it except the springs on the rear of the 3.5" kit are real stiff and are uually swapped out for the front stock springs
your also gonna need adj panhard rods front and rear as your going so high...plus you may or may not run into other little problems when you lift it but all jeeps are different.i like the look of bigger wheels on a smaller lift for two resons...you get to keepy yor center of gravity at a good hieght, and 2 the cops wont be on your arse about it
that why im running 2.5" coild with 1" spacers and like i said iv got plenty of room for 35's but if cops do pin me ill just take out my spacers and all good
do a search mate you will find heaps of info, save us repeating ourselves everytime a new thread is made
