Videos for Banks' Power appeared in my YouTube feed a few weeks ago, so I thought I'd give them a shot. A year or two ago, I toyed with the idea of getting a custom differential cover for my Gen III. After watching these videos, I'm glad I didn't go that route and drop that kind of coin. Gale does thorough testing and goes into great detail with his analysis. AFIK, Part 3 of Do Diff Covers Work? hasn't been posted, yet.

 

I'm also interested in seeing the results, My guess is that it won't be much difference in temp compared to the stock cover. I doubt that most daily drivers even towing will see 336*

 

I've been watching this series too. You just know Gale is going to put his own cover out at some point. I'll be in line for that cover.

 

Actually, he's pointing out that the "fancy" covers are starving the pinion bearing by interrupting the proper flow of the differential fluid. They're also casing an increase in temperature of the fluid along with aerating the fluid. Long story short, they're doing more harm than good, so the vehicle owner is better off with the stock differential cover.

It will be interesting to see what his final results are, and if he'll be offering his own version. I have to say that unlike most presentations, he throws a lot of great information out there but doesn't bore me at all.

 

I've always had my doubts about those covers. Thank God for someone like Gale Banks to invest the time and money to shed some light on this.

 

So here we are, end of October, and he was supposed to have part 3 out in the middle of September..... Wonder if he discovered that this was going to be more work than he thought.

 

Unlike Elon Mush, Gale strikes me as a non-bull****ter. He's most likely taking his time and doing it right. He has said all along that he is either learning as he goes or every experiment yields results that weren't expected. The data he is collecting, along with the results, are probably having an effect on his progress. That's all good, because no matter how technical he gets in his explanations, I don't get the least bit bored.

 

Yeah, the stuff he was talking about made a LOT of sense. Though I think as an 'instructor' of sorts..... he leaves a bit to be desired. That said, the vids are VERY informative. Looking forward to the next installment.

 

The clear covers sure were eye opening.

 

I wouldn't think there is even a need for those covers if you stay close to the rated limit of the truck and keep good fluid in it. Interesting stuff none the less.
