rear end...Are all 2500's LSD?
I assumed they would be, but the other day I had a spirited launch and I left one long black strip. I lifted it up and spun the tires and one went clockwise and the other counter.....so I am lead to believe I don't have a LSD. So any suggestion?? I've read good things about the trutrac and I don't plan serious rock crawling, Im off road mostly in Socal and Az and am on 35" tires. Also would it be worth while to upgrade to 4.11 or should I stick with the 3.73's?

No, not all rear ends are LSD's. THe ones that are, are a gear type in the trutrac mold. Reviews on the efficacy of the Dodge LSD are mixed. Sometimes it is like not having one at all, other times ok. At best it may be "adequate". If it is that important in what you do with the truck, you may consider something more aggressive. Otherwise, for a mostly street driven truck, the stock LSD is, well, "adequate". No one is going to rave on it for sure.
On the gear ratio, it is going to be a performance vs mileage compromise for you given the 35" tires... it is individual choice.

So what is the "best" if dare to ask. I don't want something that is barley adequate. I've seen the ARB air lockers seemed over kill. but if I only have two options trutrac o ARB.....

Eaton makes an E-Locker for the Dodges. Better than ARB because they work on an electrical current/magnet versus an air compressor/compressed air. That way you have the best of both worlds....an open diff for snowy/icy conditions, and a locked diff for off-road stuff. Their stuff is industrial grade and very good quality. And no compressor noise/realiability issues.![guitarist](https://www.dieseltruckresource.com/forums/images/smilies/guitarist.gif)

The dodge LSD is a modified version of the old gleason worm drive. very efficient, very strong, and very durable. IMO, and excellent choice for a general purpose 4x4.
One of their advantages is that they're adjustable for torque bias. If you're doing the One Wheel Peel, maybe yours needs to be adjusted.
The other thing to remember is that it's a Limited Slip differential, not a No Slip differential.
The one down side to this type of differential is that if you lose all traction on one side and have excellent traction on the other side, you aren't going anywhere. It can send all the power to the no traction side. Tha's a nice feature in racing, not so nice on snow and ice.

Advocate of getting the ban button used on him...
Pull the diff cover and look at the carrier. If you're not sure, snap a pic and post up. If you see 4 gears and nothing else, it's an open diff.
