Hey guys I finally wandered over to the dmax world and bought a 2008 Duramax with a whole bunch of goodies done to it. I noticed though that whenever I lose traction rather a little slick mud or driving out of ditch etc it will just one wheel peel forcing me to drop her in 4 when it should not be needed. I then did some digging and realized my truck doesnt show the "G80" code in the glove box but has the gt4 code. Originally I figured the diff was having issues but now Im not sure exactly what to figure. hoping you guys here could help clear the air on this. winter will be here soon and I sure hope it wont be one wheeling everywhere lol. which leads to my next question of if there is an aftermarket conversion around to build up the rear end to be auto locking like the G80s or if there is something better? thanks for any help!!
One wheel peel?

If you are not using your truck for serious drag racing or sled pulling competition, I would recommend against a Grizzly or Detroit locking differential. For a normal daily driver, a stock Dodge limited slip (made by AAM, the OEM of the rear axle in our trucks) is a good, affordable option. The Detroit TrueTrac is the same style differential as the AAM unit, but it is supposedly a little more durable with a higher toque bias allowing it to transfer more torque to one side or the other in situations with high traction differentials on opposite sides. Both are gear operated torque sensing differentials that do not use any clutches or "wear parts" to keep both wheels turning the same and work very smoothly and seamlessly on the street without any driver input. They're perfect for a daily driven truck.
Aam opens in the rain alot. And in some other situations, but launching it never failed me. It's basically an open diff just doesn't open quite as often as a spider gear setup. My brother bought his recently and it ran almost 800 with bearings installed.
For that much $$$ I would go with the tru trac. I ran one in a 1500 with about 330rwhp and beat the snot out of it. Daily burnouts, offroading, drifting, etc it never missed a beat. Granted its a lighter vehicle but thats my two cents.
I have no idea. I've never been in a truck with a TrueTrac. I only know what I've read about them. I installed an AAM diff in a truck for a customer/friend, and as far as I know, he's quite happy with it. They can be found online for around $600 shipped if you look. I think the TrueTrac is a few hundred more.
I have put some tru tracs in and like them. nothing to wear out. quiet and no issues turning and always seem to engage. I heard that if you have a tire off the ground they down always work unless you apply brake pressure. tried this in my jeep and it worked.
thanks guys i figured there would be options out there! now any sites too order from that you know of to get the best deal and support?
I'm thinking back to the old gm commercial where they had rollers on one side of the hill, and only the g80 pulled up the hill. The dodge did not. Maybe with the added bias of the Truetrac and a little brake assist it would? I've been stuck and if not for the g80 I would have been screwed. But, on the street I one wheel peel all the damned time. It's a fussy bitch. Lol
My understanding and experience is GM uses a torque lock differential. To lock you hold the brake and apply a little throttle (torque) and it will lock both wheels, release the brake while still on throttle and both wheels should spin. Has worked for me many times. Just my experience and how it was explained to me. I've had 3 GM's that worked this way for me. '02, '05 and currently an '07.5.

Lol not quite
hahaha
I'm pretty happy with my true-trac, although it keeps me on the edge my seat when it's wet out
