My advice would be to set a budget first and then look for a kit that will suit your needs.
getting 35s under a JK is pretty easy.
for the money and easy of instal the Old Man Emu 2.5" lift springs and matching shocks give you a great ride on and off road without all the headache of lifting higher.
Terra Flex, ProComp, Rancho, Rock Krawler, Poly Performance's Synergy line, Rough Country, Metal Cloak, Rokmen, Rustys, Clayton, Currie
There are too many options. I'd stick with no more than a 2.5" lift for 35s.
personally I lifted 4" to run 40s and I'm bringing mine down... there is way more room in my fender wells than 40s need.
