Thanks
I've been researching this too, and have learned a _little_ bit.
First, the Torsen Limited Slip is the same system used in the Hummer
The Torsen is a load-balancing differential. It doesn't just lock the rear axles together with the same torque application like standard limited slip or locker rear. It will actually shift the torque from left to right on the rear axle as needed, giving the most torque to the wheel with the greatest traction. As I understand it, 100% of the available torque will be spread across the rear axle, with the largest amount going to the wheel with the most grip. It will not 'Unload' like a standard differential does either.
It also free's the rear wheels during cornering, preventing the binding and chattering that can be experienced with standard Limited Slips and their clutches.
It sounds to me like it works like a center-differential does in high-end 4X4's like the Lexas, Land Cruiser, etc... where it balances the torgue from front to rear depending on which end has the better grip, except in the case of the Torsen it does it from left to right across the rear axle instead.
The Torsen rear-ends are supposed to be considerably more heavy duty than the standard locking axle.
They are expensive to buy if you do it aftermarket. From what I've read, to buy a Torsen equipped rear-axle would cost around $3500.
Again, this is just what I have gathered from reading on the subject, and I make NO guarantee's that it's entirely accurate

Torsen is a gear driven Limited slip vs the clutch driven one in the standard ls.. I believe the torsen costs about 350-400$ or so +installation. Also they only make one for the ford 8.8" rear not the 8.8" front or the 7.5"

It is my understanding that you cannot install the Torsen in a standard rear assembly, and the entire rear end assembly, axle's, tubes and all have to be replaced.
Again, that's the impression I've got from the articles I've read about it.
