I'm looking at getting a dana 60 my my car that is mainly street driven with a few trips to the drag strip every now and then. Would I be better off with the True trac or trac-loc unit? Any advantages or disadvantages to either? Thanks

The rear is listed as coming with a trac-loc clutch posi with the 35 spline true-trac as an upgrade.

Are you buying a new Strange s60 ? they offer as an upgrade the Eaton AND Strange helical carrier, the Strange unit is a better unit & cost more than the Eaton.

I don't have any experience with a True trac but the Trac-loc came in the Dana 60's I believe somewhere around 1970 and newer and were not that great of a posi, it didn't take alot of torque to break them loose and they wore out fairly quickly. My preference would be a Powr-Lok that the factory used from 1966-1969 and I believe the aftermarket makes them. In all my 8 3/4's I run the Power-Lok posi's (oh the purists will correct me on it being a "Suregrip" and not a "Posi" oops) and they work great and you can set them up fairly tight or looser depending on your preference. Here is a link to Dr Diff he is a great source for parts. https://www.doctordiff.com/drivetrain/dana-60/

If you're buying a brand new complete unit, get the Strange S60 from Dr. Diff.
Always heard the trac-locks are pretty weak. The factory Power-Lock is a much beefier unit. Both of my cars have spools and my dad's road runner has a Power-Lock in it.
I have a Moser M60 under my 'cuda that's been flawless since 2003, but it doesn't have the convenient side adjusters for setting backlash like the Strange S60 does.
You could always save some money if you're willing to do some work yourself and cut down a truck Dana.
