well, I went with the 30 spline front and rear, ox lockers. Im not going to upgrade the u jounts because I believe Id rather them be the weak link than break a shaft or pinion, although it can still happen. I was quoted 750$ to install the ring/pinion/lockers/shafts and all new bearings front and rear from the jeep dealer in vernal utah. I have to mount the cable. I checked out there work and they seem to do good work. As a matter of fact, they even upgrade new jeeps before putting them on the lot. Weird hu? Anyway next is the 4" skyjacker lift but they also throw in the 2" body lift for 2400$ Im not sure I want to go with the body lift though.
