Like stated over and over again, not so much with 6 speeds, but they last behind the automatic.

At least mine has. 100k plus, with close to 400rwhp the last few years.

also the higher the ratio the better chance of it exploding. ive got 425rwhp and 3.23s and its fine so far. but i really want some 4.10s.

RPM, why do you prefer the Auburn type? I replaced my '83 rear (after it grenaded, from abuse) with an Auburn + new 3.73s. I sold that car and have the '02 with Torsen. I wonder if you prefer the Auburn for the same reason(s) I do...

My primary reason is the chatter - Torsens have it, Auburns don't (in my experience). Also, I have a slight preference for the behavior and feel of the Auburn.

Overall, I guess the Torsen should last longer in theory (mileage wise), and you don't have to worry about LSD additives (even though it's still recommended - though I don't know why), but I still like the feel and chatterless operation of the Auburn better.

Thanks for the insight. I don't have any chatter with mine (yet?) it seems just as quiet. My issue is the way the Torsen posi "locks" when needed/required. I like the feel of the Auburn with the wheels having some preload to them and not having the feeling of open diff-locked-oversteer/loose feeling if you really load up with throttle when exiting a corner with the Torsen. The breakaway of the rear is more progressive and predictable with an Auburn and therefore the Auburn is smoother and easier to drive on a road course fast. It doesn't give you the Jekyl/Hyde treatment. There is the wear factor though to consider...

Being that I work on our little 10 bolts,I watch the 'rearend forum'.
Since Auburns were supplied up to/including the 98 models(now 13 years since last supplied),typical failures were the 'spider gears'.
Torsens were 1999 + later,and failures are the internal gearset and the 4 bolts that hold that internal gearset in the carrier case are loosening/backing out and breaking when they hit something in the housing. Also that flange end (the part held in by those 4 bolts) is failing/cracking.
I prefer the Auburn and Eaton 'clutch-plate' posi. Been using them since the mid 60s'. Also,in the 45 years,never used a 'friction modifier additive' and never had a problem with 'chattering'
