I'm putting a limited slip rear end in my '05 3500. It's 11.50 in. 3.73 ratio. The only numbers I can find are on a sticker on the passenger side axle tube. Parts guy says none of these numbers match up. Numbers are: (T)X2DH287421591 and (P)52104 and 665AG. Any way to tell if it is Dana or Corporate w/o tearing it apart? Called the dealer to run VIN and they could only tell it was 11.50. Thanks

 

Check tag on rear end, I though ours were AMT and should have limited slip in it

 

"which rear end?"
depends on the girls....

 

Those look better than mine.

 

you have an AAM 11.5 axel. American Axel Manufacturer, or you can call them Corporate

 

Well I was close, I got the first A right LOL

 

Thanks guys.
