Not in Colorado...but, get OME 912's, no new shocks (unless stockers are bad), no new torsion bars (just crank) and you are good to go. I have not flipped my bj yet becuase that is only needed when you find trouble in aligning the front end. Thus far and more than a year later after my lift I have not had any troubles. The lift took me about 30minutes to install and I am a novice.
