well F150 springs and shackles will net you almost 3" of lift for less then about 300 bucks. Otherwise stay away from both jeep places mentioned. Xtreme jeep didn't even know what a XJ jeep was, that was laughable and at the same time bad for everyone who let them do anything to their rigs. I can give you more info on jeep lifts for cheap or check out jeepsunlimited.com the XJ forum.
