I am asuming you have ADD. With 3 1/2 inches of lift from that fabtech set up you will ruin your inner CV boots in no time. I would suggest running it at 2.5-3", though you will still most likely wear through your CV boots, it won't happen quite as fast. Just something to think about...
If you do a search on CV boots you should be able to pull up a few threads on the CV boot problem the ADD trucks have. My 04 is at 2.5" and I am wearing through my driver side boot.
