Welcome to Wayalife!
You will get a lot of different suggestions but you have to ask yourself a couple of things. How will you use your Jeep? What is your end goal? What is your budget?
Personally I wanted the best on-road ride and the most complete kit that will allow me to play on the rocks and have a comfortable drive home too. I am running 37's on a 4" EVO Enforcer kit which comes complete with coils, rear track bar bracket, longer steel braided brake lines, bump stops and lower adjustable control arms. I paired that with the EVO drag link flip which comes with a drag link that goes on top of your steering knuckle correcting your steering geometry and a raised front track bar bracket. You can choose any shocks you want to run, high dollar Kings or anything your budget allows.
