I already bought a Strange 12-bolt with a Torque-Line posi, but I was curious about something. Isn't the True-Trak similar to the stock Torsen in that they're both gear-driven limited slips? If so, what makes the True-Trak any better? I personally felt that my Torsen in my 10-bolt sucked, so what makes the True-Trak any better? Thanks.

They operate the same way, but the True Trac is waaayy stronger, especially the 12 bolt variety. If it is going to be a mega power track car on slicks go with something stronger (locker/spool). If it's a street driven, moderate power car that will see some track use on sticky DRs the True Trac will serve you fine (as well as being able to go around turns better than anything else you can put into a 12 bolt!!).

Thanks for the reply!

I overlooked the fact that the True Trac is way stronger. I'm sure the Eaton/ Torque-Line posi will go around turns as well a TT, but not as strong.

One criticism I've always had of the 10-bolt Torsen is the one wheel burnouts. Is it any different with the TT, if so why?

To cure one wheel burnouts with a 10-bolt, there's only one answer. The T2R.

One-wheel vs two-wheel is all about the torque split
limit of the chunk. The stock unit has about a 2:1 max
bias capability. Unfortunately the ratio of static to
sliding friction (mu) between your rubber and road can
be more than 2:1 (even neglecting things like the right
tire wanting to lift). But the roughly 4:1 split on the
T-2R means you'll spin both tires at will almost any time
(unless one is in sand or something).

Of course that changes things from "I wish I could
launch harder" to "I fishtail all the time". The tire not
spinning holds your back end direction, both spinning
and you're not too directionally stable. Have to learn
its characteristics, while the stocker is more forgiving
if you want to play the fool in the corners.

But I wouldn't have it any other way.

Thanks Viper, Jimmy, so where does the True Trac fit in the "max bias capability" equation? 2:1, 4:1?

As I mentioned, I have a new Strange 12-bolt w/Torque-Line Posi waiting to be installed, but I was curious about the differences between the TT and stock posi.

BTW, are Eaton/ Torque-Line Limited Slips prone to one-wheel burnouts. Thanks again.

I think they run about 3.5:1

At least the one in my Jeep's front axle is 3.5:1.

Predator

Okay Ric, thanks. That's another difference from the stock Torsen.

I used to run Auburn Pro's in my 10 bolts, never got a 1 wheel deal. They use clutches in thier posis.

I will be running a tru-trac in my new Dana because its the strongest option for a limited slip.

Predator

Thanks QUASAR, that sounds promising for my Torque-Line posi with clutches.

I think you're right about the TT being the strongest LS.

It would be cool if Truetrac made a diff for the Danas and 12 bolts/9" with much more bias (for the road racers). Or better yet if Torsen made T2Rs for those axles!

Predator

I'd be happy if they just made a True Trac for Strange 12-bolts.
