I never proposed any of the preload type aluminum diff covers, as I think those could be portrayed as having a potential performance advantage. Instead, my recommendation was a modified junkyard Explorer differential cover for the Ford 8.8 that would have added both a drain and a fill plug to the cover that had magnets on both of them, and included cooling fins and ribs for strength and lower temps to increase component longevity and make fluid changes easier. I wasn't suggesting one of those "expensive" GT500 kind of finned covers either. Check out the following link to learn all about modifying this cheap OEM Ford cover. https://www.svtperformance.com/forum...ny-8-8.653880/
So you recommend a cover that has ribs for strength, cooling fins for lower temps but are you against one that has preload which potentially strengthens the weak GM rearend?

The aftermarket cover for the GM isn't a performance advantage-unless you count potentially being more durable as an advantage. If you want to say it is a cooling advantage then whats the big deal since we allow radiators, coolers everywhere else.

JJKJ-send it it for another try. But not everything on an SS or SLP car is legal in CMC anyway.

It doesn't make sense.
