PML Cover for our Rear End

[AzEric]

Just figured I'd post what I found out after reading about, then speaking with a helpful applications person at PML (http://www.yourcovers.com).

The proper cover for either the 8.0 or the 8.6 rear is what they call the "GM Torsen" rear cover, part number 11035 shown here:

Note that it will (barely) clear the trackbar.

I am not advertising for them, but I have been reading and looking for quite a while for the proper aftermarket cover for our rear differentials, and it is the only one I have found. It is a cast aluminum cover, so the metallurgist in me is skeptical about using it for our offroad applications vs the Purple Cranium half spider. I welcome any input and real-world experience inputs!

Cheers!

I've always been kinda put off by aftermarket diff covers. They seem, for our platform anyway, more of a bling accessory than actual function. I've been sticking with the factory cover and a purple cranium. The gears are splash lubed, and when up to speed the design of the factory cover allows for a nice circular flow of oil to get all over the gears. Those flat faced aftermarket covers don't provide that same splash pattern.
This Banks video explains it better than I.

UPDATE: I went with Purple Cranium, and those videos by Gale Banks were very educational! Thank you!
