That seems to be the best value. Since you have a 2008 model you will probably need to buy the alignment cams to get the rear alignment properly set. I bought my components separately and spent a little more.
put that kit on my wife's 07. It's awesome. I swear it rides better then stock. I need to replace her lower arm bushings (front - probaly full replacement arms out back) and it should reduce the body roll. Always been a Bilstein fan.. and they have yet to let me down when it comes to quality parts.
those guys at 4x4 have great customer service too.
