.......you see now I really have a dilemma.
Well, there is a little guy in white standing on my right shoulder that wants me to tell you that you may be able to get by with just a T-case drop for very mild driving habits, but if you think about going any higher than 3" or plan on doing any "extreme trails" you better go ahead and get yourself a slip yoke eliminator & a DC driveshaft with a slip-yoke within the shaft....especially on anything newer than 95. And yes, you will at least need a track bar relocation bracket, and possibly a track bar too.
BUT!!! there is also this other little fella on my left in red, that wants me to tell you that if your gonna build your rig especially for extreme trails to just go ahead and get the T-case drop an bolt up a new driveshaft to it and you should be fine. And that you'll probablly need to extend your front driveshaft also.
So, you can do a couple of things go ahead and believe which ever little guy you'd like. (i'd prob go with white) or just search...cause this gets covered tons. and I'm even a noob myself.
