To do a lift of that size correctly, you will have to spend quite a bit more than your budget. I recommend you go to wranglerforum.com and do some research. There is a vast amount of information there. Depending on what your goals are, you may not need nearly that large of a lift. For example, to run 35's, your will only need a 2.5" lift. With 2.5" and flat fenders, you can run 37"s, with a few upgrades in other places as well.
