our lsd give the other tire 2.7 times as much torque

a locker splits engine torque 50/50 regardless of tire spin

google torsen limited slips and there is lots of info out there

Is that what's in there is a Torsen? That's a gear driven LSD. If that's what it is, I don't feel soo bad.

Pretty sure it's not a torsen, see my post above.

Torsen would be far worse... pointless, actually. As I posted before:

Geared LSDs are less prone to wear than the clutch type, but both output shafts have to be loaded to keep the proper torque distribution characteristics. Once an output shaft becomes free (e.g. one driven wheel lifts off the ground; or a summer tire comes over ice while another is on dry tarmac when the car goes uphill), no torque is transmitted to the second shaft and the torque-sensitive differential behaves like an open differential.

I know which types do what. I ain't worried about that. I don't need a lesson in how differentials work. I've probably repaired, replaced and rebuilt more of them then most of you here COMBINED. Redneck Houston said it was a Torsen, and his word carried weight with me, because I've seen the pictures of where he HAS the experience enough to know. I haven't had the cover off one of these new ones yet, so I don't which type it is. I can tell you this.....IF it IS a clutch type, I stick by my guns. It SUCKS ASS.

First of all, I'm not trying to teach you anything, I'm simply regurgitating what I've learned between this morning and right now. I'm not an expert and don't claim to be. Take a pill.

THAT SAID, why would you want a Torsen LSD for an offroad vehicle? Actually, please tell me because I don't know why. As stated, a torsen diff becomes an open diff as soon as 1 wheel has little or no traction. Pretty much all vehicles listed here:
http://en.wikipedia.org/wiki/Torsen#Torsen_applications
that use a Torsen diff are sports cars.

Anyway, both wikipedia and a previous write-up say that it's clutch-type. That, and REDNECKHOUSTON didn't even say it WAS a Torsen diff, he just said "google torsen diff".

Take a pill? Where'd that come from? I ain't upset. Was just lettin you know what I wanted, that's all. Why would I prefer the Torsen? Simple. They don't wear out.

Apologies for the pill comment, it sounded like you were mildly upset

I'm not sure, but doesn't a clutch type work better (ie - work at all) when a wheel is off the ground? Based on my understanding, the clutches engage with driveshaft torque, thus even when a wheel is off the ground it should still function as a LSD, not an open diff like the Torsen. If my understanding is wrong, tell me

It may......WHEN it's a GOOD clutch unit. I don't think your understanding is wrong. I think it's right on the money. I've said in another post that I've had some Eaton LSDs that were Billy Bad Asses. They would drag the outside tire a little around a turn. Eaton has always made a superior product. I have measured breakaway torque on Eatons before at over 1000 LB FT. The only reason I said I'd rather have the Torsen is simply from a durability standpoint. When someone comes out with an automatic locker for the D44 in the JK, you can bet THAT'S what I'll be running. Til then, I'l just have to put up with what I have. Basically nothing.
