It is nice to be able to get going again after slowing nearly to a stop when it is a little slippery without having to grab 4wd just to go another hundred feet.
Got spoiled with the Jeep because it has a mechanical full time 4wd with no hubs. Just got it back from the shop yesterday after three months. He is slow but I trust him.

Fortunately your 2500 if a 6.0 has the same old tried and true 10.5 14 bolt (note, not duramax or dually, those are an 11.5” and not the same) that we all love and regard so much, just with fancy rear disks, Dana 70 spec axle tubes, metric lug studs and spacing, and a slightly wider wms. Internally the newer 10.5” 14 bolts are 95% identical. Unfortunately it’s got the same old gov-bomb G80 that they have had for a long time, which aren’t really known for being really stout. Don’t abuse it too bad and you’ll likely never have an issue. My 18 Sierra 2500 company truck weighs north of 12K and is ALWAYS in the sand or the mud depending on the time of year. 82,000 miles later with slightly oversize BFG and Toyo mud tires and it still works perfect. It’s when you go into it full throttle and one tire grabs unexpectedly, or you hammer it with one tire spinning hard that the governor blows up like longhair mentioned. They are quite handy when they work right.
