I also have a basic 4" lift that I had installed and drove for about six months, or about 1000 miles. It consist of springs (they actually gave me about 5 1/4 inches of lift) shock extentions, t-case drop, and a drop pitman arm. This is a starter kit that you can add as you go. i.e. adjustable track bars, quick disonnect, long arms, good off road shocks, sye. I am asking $300 and can install for free, if your going to be in the area.
