Trac-loc?

I have an '87 cherokee with a Chrysler 8.25 in the rear... i got a trac lock carrier to put in it for better wheeling... andyways, installing it is not a hard part. I am just wondering what everyone thinks about the trac-loc system? i have herd both good and bad... also, does anyone know where i can see like a breakdown or a schematic of the trac-loc carrier? it doesnt look like any LSD i have ever delt with before, it had these minor clutched beside the spider gears.... thats about all i can see... someone explain...

Does everyone agree on this pronunciation? As long as it is better than my one wheel wonder open then i dont care...
