I could do almost any trail with current articulation and that lift height/tire size. It gets the big body and overhangs out of the whay and provides more gorund clearance. I'm sure you'ld need CV shafts like on my 80.
With the pictured set up, a front CV driveline is definitely not what you would want. In order to be a candidate for a CV driveline the pinion needs to point at the output of the transfer case.
