I am running the ford 8.8 in the rear and the Dana 30 up front. I wa thinking about running a Spartan locker in the 30 and the ECTED in the rear because the cost of the cost of the ARB. I do not know anything about the OX. This is not a hard core Jeep. I only have 33's right now and might go to 35's later. I want it to be functional on the trail but still street worthy.
