Rear differential covers
I’m getting ready to have the rear diff serviced and am considering adding an aluminum cover with heat sink. Have you gone this route? Does it make any significant difference? I have 155,000 miles...

If casting fins into the housing cover solved any problems, wouldn't the manufacturer be doing that already?
They do. All AAM axles (GM and RAM) come with a finned aluminum housing.
Factory cover
And they needed it. Before they used these covers, they would cook the paint off the old stamped sheet metal parts.
Not true.
OK to make you feel better, all 11.8" AAM diffs use it.
Unless your talking about the paint peeling, in that case you're wrong.
I feel fine, only getting the aluminum cover from the factory with the Dually. I "think" only with a 4.10 and 3.73, someone please clarify.
I gots one! IMHO this cover will cool much better than the MagHytec. I used one on my 11 HO Dually. Setting on the shelf.
Paint peeling that was on the earlier AAM's from what I have read about.
I was told at the dealer by a salesman that the finned cover came on all the Aisin equipped trucks. I know mine has the Aisin and 3:73 rear end with finned cover. Salesman said it so it must be true.. right?
