I've been thinking about getting a Detroit TrueTrac installed. It's a gear-type LSD, so it doesn't need the gear oil additive, and it should last longer than the OEM piece. It's supposed to be high quality, the newer design anyway, and very smooth for daily driving.
I've also read good things about the Auburn unit, but if I do upgrade, it'll be to the TrueTrac.
