This looks to be new. Has anyone tried it yet - on the track or on the street? It has a pretty big price tag so I was wanting to see if there were any out in trucks yet.

Are you talking about the guy who "had it from a good source"? I think he worked for Yukon.

The way he was talking about it, the price seemed to be awful high...over $1000.

Not sure how similar the Yukon locker is to a Detroit, but in the offroad world, it isn't uncommon for a Detroit to be damaged/broken when an axle shaft breaks. For the price they are putting on the Yukon, I would go with the ARB.

What do you mean not a locker Josh?
The TruTrac isn't a full locking differential. If you get a tire off the ground, or a large traction difference from one tire to the other, the tire off the ground or on the slick spot will spin and you won't make much forward progress unless you drag the brakes. On the street it isn't a big deal, but if you go off the highway, it could cause a problem.

i must say thats not really true...you thinking of an open diff or a very poorly made limited slip...what they are supposed to do it sense which wheel has the most traction and sends the power to it. if i pick one of my wheels off the ground or put one in dirt that one wont even spin really just the other one or both evenly

btw im pretty sure dodges some with an open diff unless you get the option...but that i could be wrong on. its been a while since i was looking at them

I've seen it happen before. It's how they're designed. They can only transfer a certain percentage of torque. The most aggressive torque sensing type differentials transfer up to somewhere around 95%. If you have a tire off the ground or on an extremely slick spot (e.g. ice), you must transfer 100% of the torque to the tire on the ground. The only thing that can do that is a spool or a locking differential. Like I said, on the highway, it likely would never be an issue, but off road, it can cause problems.

thats true...but i mean if 95% of the torque is going to the good wheel pretty much what happens is you just break them loose and it becomes just like a lockers anyway or use the good wheel with the traction to get where you're going instead of wasting half the power on the wheel with no traction. i don't mean to argue and im not trying to be a dick just trying to get the info out there. im also not trying to take anything away from the lockers...they are absolutely great for certain applications

now the old limited slips have clutches inside that wear out and make it useless but the Detroit doesn't have them its all gear driven.
