Looking for a posi unit for 2004 2500 4x4? who makes one? My friends truck came through with a one legger and a cummins. You go noooo wheeerrreee in the rain...

 

Never used them, but http://www.ringpinion.com/ seems like a good source, although, I have not used them.

Did DC change to AAM in '03? If so, you won't have too many choices. Randy's (link) seems to have some choices.

I'm sure others will chime in.

Not that this in in-line with what he asked, but I wonder if the front locker from a PW will swap into our differentials... minor modification for power wire, and assuming the locker carrier that has 4.56s will accept 4.11s or 3.73s? I thought about the rear, but I believe the PW has the 10.5, not the 11.5.

 

Check out reiderracing.com they have a lot of information and differentials to compare.
