Just browsing YouTube and came across some differential cover development videos from Banks. With the amount of damaged differentials I've rebuilt and replaced over the years that had fancy heatsink differential covers. I've long suspected that the aftermarket covers effected the oil flow within the housing which causes lubrication issues for the pinion bearings and wheel ends.

 

Moral of the story for me is the after market aluminum heatsink differential covers are R.I.C.E. (Race Inspired Cosmetic Enhancements) and do nothing positive for performance so those who have them are no different than the Honda Civic boy that has the park bench spoiler on the trunk that adds 50 horse power.

 

Here is the video I watched.

the reasoning is sound as well.  One thing I never thought about.
