Just installed the Teraflex leveling kit. The spacer version. Really easy to do. Only took me about 3 hours by myself. Thank God for air tools. It went on just as easy as the videos you see and I am pleased with the results. Does exactly what it says it will. With the Spidertrax 1.5 wheel spacers...This is how Jeep should sell them!!! Jeep drives and handles as before. Now Im ready for the bigger shoes! Highly recommend.
