I heard from a very unreliable source that you can do up to a 3 inch lift with the stock setup, but if you wanted to go up higher you'd have to find a Comanche drive shaft to swap in it's place.

Something tells me they're the same, and that guy was full of BS. But, I figured you guys ought to know something about it.

 

I'm running 7" on a stock front drive shaft, the rear is the one that need to be addressed after about 4".

 

I distinctly remember them saying front. But rear makes much more sense to me anyway.
