Bought it as an "open box" and saved $30. This is the third kit I have installed on a Chevy 2500hd. The fit and finish is perfect and installation is a breeze if you have the usual hand tools. Make a set last 10 years and still vent to 100psi to reduce trailer squats. They are very easy to fit on raised trucks, just take a square stem or tube the same height as your traditional rear lift and bolt them together with class 8 fasteners as in the picture.
