Since reading what everyone has to say and looking at 3" kits and 2.5" kits, watching Youtube videos and various other Google returns I have decided on the Teraflex 2.5". I thought the bigger the lift the better and assumed that with a 4" lift no drive line modifications would need to be made. I now am more educated and have a better understanding. Thank you all for your advice.

 

I just got done turning the wrenches on a Full Traction 3 in lift and 35 in duratracs the 3 in was a ton of lift it took me a me a few extra hours but was doable as a DIY project. I would get the north ridge bolt kit and replace the stock ones as my Jeep had 1000 miles on it and stock bolts already started chewing on the metal sleeves
