Default Mystery Differential

Can anyone ID this differential?
I bought a rear of a friend to fix my car and this was inside. I don't think it is stock. It came out of a 00-01 WS6/Ram Air Trans Am.



I had to take this hunk of metal out of the center of the diff to get the C-clips out to pull the axles

These Torsens were stock after 1999 I think.

I have never heard of Torsen. are they a good diff? Is it a limited slip? I am guessing that no limited slip addative is needed since there are no clutches?

Torsen is a good differential...you don't need the additive unless you are getting some strange noises. Just use a good 75W-90 or 85W-140 gear oil and you will be set.

I don't know if it is technically a limited slip differential, but it will put power to both tires.
