I just got my truck and I love it to death. I bought it used, and it had 33x12.50r17's on it. It wasn't raised any (I dont think). I need some advice on lifting my truck. My plan was to lift the front with some new keys (raising it about 2" I think, i would like 3" but i dont know if keys will get it that far) and raise the back 2" with an add a leaf (I do alot of hauling so it serves as a lift and payload booster). Is this a good idea? Also, if i'm correct, the tires on there are about 33", how big of tires can I fit on it with this lift? I heard something about haveing to do something to the truck if it's raised 4" or more.
