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.

Over the years I've been a fan of looking at rear ends, but not finned aftermarket covers. Can someone tell me how long the rear differential in our 2003 Dodge dually is going to run with 242,000 miles on the clock with the plain old OEM cover towing a 40' fiver?
I was a Ford mechanic for years and worked on many a rear end. What you said bobsallyh is very true. Never saw but one rear end burned up and it was a F350 were a boy got stuck and burned it to a crisp. Waste of good money.
No it doesn't happen often, but that doesn't mean it never happens. Carmakers wouldn't put all that money into R&D unless it was worth it!
