What are my options for upgrading rear end to posi? 2001 4wd 2500

Eaton truetrac is a good option. No clutches to wear out or additives to add. Same setup in 3rd gen + AAM rear diffs.

Yeah I got stuck in the sand the other day. I wouldn’t have if it would have been posi traction. 
I’ve never needed to get into a differential. Pretty straight forward install? 

The abs tone ring will have to be swapped over. I think there’s some vids on YouTube explaining it. I don’t have one but if I ever did I’m going with that.

Is the rear end on these trucks heavy duty enough to stand posi traction? Am I going to snap axles or anything else? Any reason I shouldn’t do this?

Of course.

 

The factory LSD performs fine (when it works) and they never snapped axles.

 

I like the Truetrac because it’s maintenance free and works like a LSD. It just works with gears, not clutches.

 

You can swap in like a Yukon or other makes true posi but they’re full time so if you have ice/snow conditions it make not unlock and put you in a skid.

 

I know Eaton makes one for the Dana 80, I don’t think they do for the 70 but I’d check on their website first.

I went with an Eaton True Trac in the rear and a Yukon limited slip for the front axle. Both seem to be working great.
