Differential covers 101
PU Truck mag That answered a lot of my questions about these covers. Extra large ones may not make a lot of sense because they disturb the oil flow in the housing.

What I took away from the Banks video's so far is the shape of the cover in the center and the flush fit to the pumpkin casting promotes fluid flow up and back to the pinion whereas the cast covers impede the flow and the fluid has to make a sharp transition in addition. Other thing is, some of the aftermarket covers raise the fluid level from what the engineers set it at and that is no good either. Very impressive video's. I'm sure Gail is spending a lot of jack making them and really irritating makers like MagnHytek.
Only thing I wish was my stock cover (Corporate 10.25) has a drain plug in it. I have to pull the cover to drain mine, something I do every couple years. My front diff (Dana 60 full floater has a drain plug.
