Detroit TrueTrac: Anyone ever use one, know someone who did? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was looking at different posi units for my truck, and I seen that the Detroit TrueTrac is only $200, and it says it can be installed by someone who is mechanically inclined, no need for a professional install. This posi unit was also recommended to me by a friend of mine who races circle trac. He said that since it doesn't use clutch packs, it's MUCH stronger. The theory is sound, but are they as good as an Eaton Posi?
FYI: This truck will NEVER be driven in the snow/ice. The most it will be driven in, is rain.

Detroit Locker is one of, if not the best posi unit available, it uses no clutches.

Not sure about TrueTrac, might be a play on the Detroit Locker name....

I have two of them. They aren't any easier to install than any other differential carrier, so I don't know what that meant that a mechanically inclined person can install one. That is true, but you do need a variety of special tools, good instructions and a lot of patience.

It is a limited slip differential that uses gears rather than clutches to engage and disengage. It is made by the same company that builds the detroit locker which is a locking differential rather than limited slip.

It is very stout and will wear longer than a clutch type posi. It won't fly apart like a GM gov lock. If I could fault it for anything, it would be the backlash in the unit that gives it a little 'clunk' similar to a slightly worn u joint, but that's just the way it works and I've gotten used to it.

All in all, I'm happy with mine. Where are you finding them for $200? They are closer to $400 all the places I've seen them...
