I'm looking at 3 different units from Eaton. My car sees some road use and will be seeing track use most weekends this summer.

The first is a standard Eaton clutch style posi unit.

The second is a Detroit Locker Truetrac. I like this one because it's the newer style helical gear setup which means there are no clutch packs to replace. It also silent like a standard posi and cheap. i just don't know of anyone using them and if they hold up well. Here's a picture incase you haven't seen one.


The other is an old school style Detroit Locker. My dad swears by these, but the noise is a major turnoff and I've heard bad things about driving around town with them.

I would really like some input from guys who have used these products, but any knowledgable input is welcomed.

 

go with the detroit true trac, i have an auburn and it sometimes does a 1 wheel peel, true trac is flat out th ebest unit out there
