    Guys, I don't know a lot about diffs so could you please tell me what this is in my carrier. That being the orange springs and the anodized parts. I have never seen anything similar. Is it just an older part from my 12 bolt or an older posi or what? Or is it just stock and I'm just ignent?:D

    I really can't tell if its stock or not. I don't have much knowledge of that. However it is some kind of Posi. If it still works you should be happy that is one thing you didnt have to buy!

    its an aftermarket limited slip, but I don't know what brand for sure. I am not up on all the LS's so someone else will have to identify it.

    That my friend, is an Auburn Limited Slip. It's a good decent unit. You'll like it.

    wouldn't it lock up around corners? so shouldn't he have felt/heard it in 1.5 years of street driving?

    No, posi's don't lock up in the corners unless you really get on it. Especially with tall tires.

    is there a set amount of torque (possibly adjustable by different spring weights?) that you have to apply to get it to lock? Otherwise how does it not lock when the outside axle shaft is spinning more revolutions around a turn?
    I figured it would be the same as if you were going through some mud/snow/sand/etc. going straight and one tire starts to slip...

    limited slips like that do not ever lock up the provide a certain amount of torque bias

    Nope, not foolin'. That is an Auburn unit. Mine was real tight. Straight away's it was locked up. I could roast both tires at the same time, just like it was locked. It would release around corners, but would immediately go back to a lock pattern. I guess my 350 had so much torque w/4.56's that it kept the bias in check. They will help you out in the MUD pretty good. Big difference between that and open. Just don't get big headed and think it's a locker because you'll get stuck and be like "Oh Crap!"
