Detroit locker posi unit??

Good info here http://www.4x4icon.com/offroad/detroit/detroit_noslip.htm

I have had 3 of them over the years in different "street" 4x4 I think they all had about a 1/4 turn of slop. It does take awhile to get use to them, I have never had a problem on ice or snow so....

Now I have one for the Dana 60 going in to my Dart they are super tuff!
