Still on the fence in regards to a limited-slip differential... heard about these and their benefits. Retails around the cost of the Boss 302 Torsen and sold exclusively through Moser Engineering, I think. Anyone out there with some knowledge of this piece?

Here is the website, admittedly I've never heard of this diff before you posted.

 

I have the stock 8.8 and 3.31 gears. If I was going to go to a limited slip I'd probably bite the bullet and just swap the whole rear with the Ford Racing rear w/ the Torsen and 31 splines - much cleaner install and then I'd be sure I have a good rear.

After installation I would estimate they would be around the same cost. Just a thought.
