I posted last summer about a limited slip rear to replace the stock open
rear. I received a few suggestions, including going with an Auburn, but not
sure with the cone design, etc.

Just to followup, I went with a Dertroit TrueTrac, since they finally came
out with a version for the Ram 1500 9.5" rear. I was waiting since July when
originally told it would be released, but they pushed it up until late Sept.

I must say this rear is awesome! I just drove it around during a recent
snowstorm in the Philly area figuring this would be the real test. I even
kept it out of 4x4 for awhile just to see how the diff performed. In 16
inches of snow, I was driving thru unplowed streets and even tried it on a
deep snow covered field.  It locks when you need it and it's very quiet.
Didn't slip once, even while going uphill.

Please don't think this is a sales pitch. I have NO affiliations with
Detroit Locker or Eaton (who just bought Tractech Holdings, Inc., the owners
of the Detroit diffs).  I just wanted to share my experience with this
awesome diff, and if you're looking at a new streetable diff and not worry
about clutches, check this one out first. It's a true mechanical limited
slip with NO clutches, all gears. Got to hand it to the guys who developed
it.
