Torsen T2R torque Sensing Differential...Where to Find One?

[Hot Air]

Anyone know where I can find one? Is there anything that works as well for autocrossing?

Thorsen diffs are a little different and have been used for OE before because they don't burn out, but they still don't work the same as a posi. Get a good Eaton unit and you'll be happier Conrad.

Check out "T-2R Applications"

I'd like to compare it to a Detroit True-Trac (another helical gear design)

X2 for the Eaton unit! I personally know quite a few people who have already ran the Torsen units in their cars and they wasted them, they then went with the True-Trac and after years of autocross use they are still going strong without any problems!

There are MANY products out there that offer options but the guys out there pounding on their cars on Road-courses & Autocross seem to weed out real quick what works and what doesn't.

How are those True-Tracs on the strip and street?

I suspect they are good for street but I wouldn't recommend taking one to the strip and launch off a transbrake with real sticky slicks.

I understand Summit has best price for the Eaton (Detroit Locker) TrueTrac. They have one for 30 spline axles (aftermarket). Stock axles are 28 spline.

When I talked to the Eaton rep at their booth at power tour, he was confident the trutrac would do anything the clutch type would do, except wear out clutches. The only downside according to him was the additional cost.
Is there a reason you don't think it would work at the strip?

I talked to rep for T2-R several years ago about their unit and when told that my GN might well see some dragstrip use, he told me the T2-R was not a good application. I did not ask him why...should have. I would go with the recommendation of the Eaton rep now.

Latest issue of Popular Hot Rodding has write up on their Muscle Car of The Year (MCOTY) contest. 12 cars showed up. 7 had Truetrac, 2 had Wavetrac, and 3 didn't tell what they were running. The Wave
Trac is a newer design that supposedly solves some of the problems of older units. Not sure who manufactures it but available from Moser and The Driveshaft Shop in Salisbury, NC (my back yard). Supposedly the WaveTrac is available for GM 8.5" but have not confirmed this yet. WaveTrac runs $1,100 and TruTrac is around $450 so price differential is significant. Not sure if it is worth it...time will tell.

The reason is that Torsen type differential can go peg-leg under low traction conditions. This usually happens in the water box. Also, under high loads the power transfer can shift from one axle to the other and back. I have a Torsen in one of my street cars, but still prefer the clutch type posi differential to it.
