This Banks Cover video shows pretty clearly how the cover can alter your trucks performance. I’m not promoting it. I think the details on how they instrumented the testing is amazing.

Banks Dif Cover

Impressive, I wish I was that smart.

Bet it doesn’t take much of a rock to the corner of it if off roading to bust it.

Pretty intensive testing program. Very interesting.

Have any of you measured the temperature of your trucks differential cover, with an IR gun, after a good tow? I towed for years and never gave it a thought.

$475 bucks for a diff cover. How many differential failures have you had? That's tons of miles to pay back a very small fuel economy gain. It's neat that he puts all the testing into his stuff.

So let me get this right for every 10 miles I save $.045 ... wow
