I saw a blurb on another forum that said something to the effect that they revised the T2R slightly and so ones that are being produced now are not as reliable as they used to be. Has anyone heard the same thing, or has anyone bought a T2R recently?

I was planning on buying one for my next mod mostly for the added torque bias. If the new ones are not reliable anymore I might have to look at something else like the Trutrac I suppose. Does anyone know the ratio on the TruTrac by any chance? Besides strength is there really any advantage of a TruTrac over the stock Torsen?

Thanks

My T2R is a few years old and it has acquired a hairline fraction in the case. Others have had similar problems but I don't know the age of theirs. I'm switching to an Auburn racers differential for a few reasons:

- T2R's have been on nationwide backorder for months without an ETA
- T2R reliability concerns
- Auburn racer's diff is $469, T2R is usually $500-600
- If the Auburn breaks, Auburn replaces it with a new unit for ~$140.
- I don't drag race

I know Strano Parts has the racer's diff for $469.

Interesting. So how does that compare with the TruTrac in a straight line, around the curves, and in a daily driver?

The "racer's diff" has more pre-load than the Auburn Pro, so I'm going to guess that it has a decent bias advantage over the Truetrac. But I also hear that Eaton will build you a Truetrac with more bias than the "stock" one??
Where the bias of the T2R fits into all of this is anyone's guess.
If you ask this over in the Road Race/Autocross forum, or on frrax.com, you might get more definitive answers, as I'm sure Sam Strano knows.

chicane, do you know what's going on with all of this??

Maybe I will go over there. All I have gathered is the stock T2 is about 2.5:1 and the T2R is either 4:1 or 5:1. The default Truetrac is supposedly somewhere in between, whether that means 2.6:1 or 3.9: 1 or simply something like 3:1 is unclear to me.

I might indeed have to go over to frrax.
