I found a 3 in. lift.  It is just a budget spacer lift.  Comes with new shocks, and thats about it.  Do I need my t-case lowered or anything else.  This lift doesnt come with any of it.  Its cheap and only plan on having it for a couple years.  I have a 2001 Wrangler "TJ", and plan on running 33s.  

it will work but you should get a drop pitman arm for the steering, rear track bar relocation bracket, and an adjustable front, expect to have some driveline vibration although cam bolts can be used to adjust the pinion angle to get rid of most of it, and be sure not to disconnect the front sway bar while wheeling or the brake lines will get stretched. also reroute the fuel pump wireing, the new found travel from the longer shocks will yank the harness apart.
3 inches is the point that things really start to get out of wack.
may be better of to check into a rough country kit or other, that has all the pieces for around 550.
