I am reading mixed things regarding driveshaft issues with this lift. I have a 2 door x manual tranny and want to put a 3 in lift on instead of a budget boost. I would eventually like to upgrade to the 3 in long arm system, this is why I have been leaning towards the teraflex kits. Do I have to purchase anything else other than the 3 in kit without arms to get it rolling ok?? I can upgrade things as I go , just kind of on a budget to start with. Anyone with a 2 door running this kit without problems???
