Yes it is, its not a clutch type like stock though. It will work fine for some uses.

ahh ic. so when he says "This differential offers 40% locking on acceleration" that means lsd? and also the lower the percentile means more of BOTH wheels spinning?

ahhh sooo closeee..

It is a torque bias differential not a limited slip differential.
Like the seller said it would be great for stret/autocross/light de duties.

I have the true LSD from Gaurd Transmissions and it is the best available for dedicated track cars. It is what Flying Lizzards use in their GT2 cars in ALMS ( they take the stock Porsche unit out...)

That's a great price for anyone who has a street legal 944.

A TBD like posted has a certain percentage of lock up upon acceleration.

A true Limited Slip Differential (LSD) has both a lock up on acceleration AND a lock up on deceleration. The one I have from Gaurds is a 50/80 lock up.
Great for track not so for the street.

The Guard TBD for sale is similar to a Quaiffe brand and to the 968 m030 diff. It is great for autocross and street applications, and does not have the wear issues that an lsd does (no clutches to wear out).

In my understanding, and limited track experience, a true lsd is better for track due to the lockup on decel, which helps keep the car more stable on decel and discourages spinning/oversteer while trail braking. Maybe someone who knows better will chime in.

Thanks for the clearification....

a few days ago i tossed the package i got from paul guard last summer. your answer is about what i read.

i went for a 951S instead of a 968 because of the lsd being better on the track. of course if i found a 968 that was right, and that guard torsen unit was around you would not hear me complaining.
