Replacing limited slip.......

Already not impressed with factory clutches in my 250 after only 3K miles. I know the detroit locker is the bullet proof way to go but its a little more aggressive than what I am looking for. I want to replace it with whatever is in my 08 dmax. It locks when I need but otherwise you wouldn't know it was there. After 120K miles it still locks like a champ even with one tire on and one off of pavement it will lock up. Anyone have any idea what type of locker GM is using or a similar set up that someone has had good service out of?

You can't go wrong with a Detroit TruTrac, mine works great.

There is no lock up at all in these 08 Rear ends. I can get stuck in wet grass.

I'm pretty sure its some sort of locker. I can hear it go "clonk" and lock and if you immediately turn occasionally it will stay locked and year hear the inside tire slipping.

If I turn and apply power my TruTrac will chirp the inside tire every time.

Already happened to me twice. Once pulling off from a red light beside a buddy with my boat behind me and the other leaving a friends house. Both times wet road of course. Embarrassing from $50K truck with only 3K miles. I've done some reading and searching but still unsure which model to order. Anybody know which trutrac I need to order? 2010 250 3:55 limited slip.

This is the one I put in my '03, not sure if the 2010 axle has the same carrier or not, but I think it might be.

Possible they changed spline counts, but you could call Randy's and they would know for sure: - TT 915A550

My dually is 2wd and I heard this type of diff will help it tremendously in the snow and slop. Being a DRW is it going to hurt anything running a rear like this as opposed to a single?

What would one expect to pay to have it installed?
Thanks.
