    I've never tried those two but have had great success with the Auburn, other than a used one I bought off of Ebay I should have known better than to buy a used posi!

    nope, those are G80's and they will eventually explode on you.

    OK an Eaton will wear out pretty fast they are a clutch and steel type posi alot like u would c in a automatic transmission, true track seem to be ok but a worm gear rear end is likely to explode under hi hp with slicks. An Auburn HD would be the way to go in my opnion. They hook up great and you can have them rebuilt.....

    You can't rebuild an Auburn but if you burn one up while in warranty they will replace it for about $120. That's cheaper than the rebuild/re-clutch charge on any other diff.
