yes and no. You will need to everytime you adjust your suspension. Some places will do it and gaurantee it for a year so you could just take it back to them I guess. As far as adjustments, there is a small allen screw in the ring that holds the coil in place that needs to be loosened first, it keeps the ring from spinning while driving. Then you take your wrench out and get after it. make sure the vehicle is jacked up. Also I took off the handle of my floor jack to put the pipe over the adjustment wrench cause you will need the extra leverage. Once you have it level and where you want it, then get an alignment and you should be set until you change it again.
