well have you researched it, it's total crap. it's not a locker and not a posi.

basically it's a binding unit. when enough force is put on the plates it wedges itself in the carrier and jams the two wheels together.

I don't know about you guys but I don't want that product in my car, It most likely will ruin the rear end over time, and I sure don't want to fork out a couple grand to buy a new rear diff, when I'd be better off spending $2000 on a quaf unit.
