In reference to the lift kit question, I would take some time and utilize the search function in the TJ Forum. Your question gets asked a lot on here and there are so many threads about lifts. This is what was recommended to me when I first got on here.
Once you narrow it down to one lift or the other, or a specific lift kit question then re-post. But for now since u r at the beginning stages of looking into lifts then try the search function.
