anyone out there ever hear of the Auburn High Performance Series Differentials (jegs part # 109-542057). if so are they any good. i'm looking to replace the stock posi unit in my 10 bolt. if anyone has any other aftermarket posi unit in their car and likes it please let me know. thanks, dan

I've got that one on my car. It does what it's supposed to.

thanks for the reply. is it a direct replacement for the stock unit. are you happy with it.

Yeah, its a direct swap. Just make sure that you get the one with the right axle spline count and the correct carrier. Yeah, I'm happy with it. Both the back tires spin when I stand on the throttle and it hasn't broken, that's about all you can ask of a positraction unit.
