Auburn vs. Eaton Limited Slip Differentials

[outrun]

My GM Corporate 10 bolt is factory equipped with an Auburn unit. Come overhaul time whenever that may be Auburn and Eaton are the options. I have had no problems (sans some gear whine) with the unit for 225,000+ miles. Of course fluid intervals were conservative using the finest available synthetics (Redline, Amsoil, etc. During later production years Eaton became standard equipment in my application. Come overhaul time which should I go with?

Interesting topic. I've been thinking of adding a Detroit (Eaton) TrueTrac into my truck's open differential. The idea of a clutch-less LSD is more appealing since the upfront higher cost means less servicing later on.

I checked with a local 4 Wheel Parts shop, but for some reason they told me that I should go with an Auburn instead because they claimed the TrueTrac is discontinued, even though their corporate store still sells them. ???

I think I'll still go with the TrueTrac...

I put an eaton ratchet I got nib from Ebay in an S10 blahzer 3.42. (for $190 - major score)

It made that little SUV unstoppable in PA winters, and prolly an auburn would have as well.

but heck, I find my trak-loc fords pretty good when you add an extra plate to increase side load.

In some (most, even??) apps the True Trac is less $$$ than most of the clutched diffs, brand new for brand new.
