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.
