Anyone make a Torsen diff. for the 5.5 gen?
Does anyone make a Torsen differential for the 5.5 gen? Something similar to a Quaife ATB diff. is what I'm looking for.
I'm not able to search and I've already googled it with no success, so don't bother flaming me.
Any/all help in this matter is appreciated! Thanks much.

Really? First I thought they were called ATB diffs like Quaife's automatic torque biasing diff., then I learned that Quaife was just a brand.
Now I'm being told that they're called Torsen type diffs. Hopefully I've got it right this time! lol
So for they record, they're called HLSD's (for helical limited slip diffs), right?
Thanx much!
Any personal experience with it?

Theoretically, if you applied power to a HLSD in slippery conditions, it will act like an open diff. You wouldn't be able to tell the difference. The reason is because the HLSD is a torque-sensing system. It reacts to torque loads placed on the system, which binds up a set of gears riding on a helical bias, which binds up the diff.
What that means to you is that if you lose traction in one or both wheels, the HLSD no longer senses any torque on the system and the gears won't lock up the diff. This is the opposite of a VLSD, which senses inequalities in wheel speed. These will lock up in slippery conditions if one wheel lose traction, but not if both wheels slip at the same rate.

Torsen is a TYPE of lsd.
here are some linx explaining tis stuff:

thats called torque bias. 
THANK you...
Torsen bought zexel, or the other way around. the name is synonymous with a helical gear locking differential. they invented it, AFAIK...

Torsen = Torque Sensing
Helical = The gears in the diff are cut in a helical pattern
ATB = Automatic Torque Biasing
LSD = A diff that doesn't let one wheel spin faster than the other by more than a certain amount
Any diff labelled "Quaife", "ATB", "Torsen", or "Helical" does the same thing: It acts like an open diff (good for turn-in) until one wheel encounters more resistance than the other, at which point it takes torque away from the faster-spinning wheel and channels it to the slower-spinning wheel. Some are better than others, but they all have helical gears and they all redirect torque. They can also kill torque steer, and they will not die for a very, very long time.
This is different from a plain LSD, like the viscous (VLSD) and clutch-type (e.g. Cusco, Kaaz, Phantom Grip) diffs. Those will prevent one wheel from spinning out of control by limiting the amount that one wheel can spin without the other. They won't redirect torque, they can compromise turn-in, and they won't help torque steer much, but they're much simpler (i.e. cheaper) and can be less intrusive for things like drifting.
NEITHER OF THESE TYPES IS ACTUALLY A "LOCKING" DIFFERENTIAL, no matter what anyone says. "Locking" is just a term that people throw around so they don't have to keep track of all the different kinds of non-open diffs. The diff types above will prevent traction loss, but they will NOT lock the wheels so that they spin together at exactly the same speed -- which is good, because that'd kinda suck for anything except going in a perfectly straight line on really bad surfaces.

It's not easy to describe the feeling (for me at least). Generally, one tire slips for a split second and then stops because the HLSD kicks in. I've only done it a few times on accident (usually on hills when it's wet), but I can tell a difference compared to a car without one. You can also tell when accelerating rapidly in curves.
