I'm not sure what everyone else thinks but Ive ran Rustys 6.5" lift on my 86 MJ and 87 XJ and loved them. It took a few trips for the springs to break in but after that they were awsome. And I know he stands behind his stuff. I rolled my MJ broke the track bar and bent an uca. I called him and talked to him for about 15min then about 2 weeks later I got a new extra heavy duty track bar and new upper with no cost to me. can't ask for better than that in my book. If I buy a new lift anytime soon it will be Rustys. But thats just me lol..........JT
