Axles-Gears-Powr-Lok setup

I've used several in Mopar, Chevy and Ford products. The PowerLock is the best limited slip unit, bar none. They are very strong. In a straight line, they are darn near a spool, especially under power, because the clutches "ramp up" and grab from the applied torque. They will even stay locked if you go around a turn under a decent amount of power. I would get it from Dr Diff. I think he offers a forum discount.
