Carbon fiber trac lok clutches?

I got some carbon fiber trac lok clutches and were wondering if they were worth a crap. The guy that sold em was pretty knowledgeable in rear ends but I still wonder, considering I read to go with ford only clutches. Did I just waste my money on $hit, or are they worth putting in? They cost only a little more than the ford ones which makes me curious.

Just checking because I didn't want to put in something that will cause problems for me later down the road, requiring going back in the rear.
