If you run 33s you could get away with probably a 3.5” leveling kit and upper control arms
I would suggest spindles as well and keep a close eye on cv axles too, I have 33's on a 3.5 leval kit and ended up getting a cv axle that actually extends and retracts and can handle greater angles. This is on an 05 so may not be of help but anything you lift encounters the same obstacles. If I had to do it over and I will just buy the complete lift kit you can find them whether it be 4 or 6 " you will just have to put the research time
and everyone on this site is knowledgeable and helpful. But my opinion is just spend the money for a complete lift kit and be done or you will buy everything eventually piece by piece anyway costing more. My opinion
only as well, 6" lift is not over the top. Just speaking from my personal learning experience and opinions.
