I have the Revtek 2" leveling kit, real easy to install. Made of cast aluminum, not poly or rubber like some others. I really like this kit, no problems so far (about 6k miles), very high quality. Took about 1½ hours to complete, no alignment required. If you do end up getting this kit, do yourself a favor and remove the track bar bolt right away. When you look at it you will think you can do it without removing it... you can't. Hope this helps.
