[@tedshredz58]

Industrial mechanic here. I REALLY like this vid. The bearing and lube theories we used for reduction gears was, while static, the lube sump level had to be 1/3 of the way up the lowest rolling element (bearing or gear) in the assembly. That would allow for the distribution of the oil by drawing it up and over the other elements. Any deficiencies, like all of the ones pointed out here (cooling, distribution of lubrication), is a design issue. Well done...

[@ArcticAstrophysics]

The fact that it shears off if you do run over and hit something is a good design because it means you wont won't crack the housing and lose any diff fluid it will just shear the fins off

[@ToAstYNaChO]

Yes, That's the point.

[@mememaster147]

I feel like it would be better to have an Xtreme Offroad™ version without the scoops and with fins that only extend to the edge of the cover, specifically for use in environments where you're likely to whack the diff on something. I doubt anybody will be doing 55mph offroad anyway, so the scoops probably aren't as much use at low speeds.

[@noxious89123]

​@@mememaster147 You can just do a rapid uninstall of the scoops yourself, with nothing other than a 4lb hammer! :D

[@SCwrestlerTTSB]

@@mememaster147 the only thing is with the exception of Baja racing you aren't going to get air flow off road over the cover to get cooling anyways. That's why most of the off-road differential covers are extremely robust and some of them have an exoskeleton girdle to protect it from getting dented in or broken. They are much more worried about that than they are the airflow

[@alangwin3891]

This guy is quite the salesman. The stock covers are fine as far as fluid temp is concerned. The MagHitec covers have a port on top for a temperature sending unit and yes they run cooler than stock. Then there’s the millions and millions of real world testing without any issues that I’ve heard of. The reason guys have been running these flat covers for the last 30 YEARS is for the drain plug, dipstick, fill hole and you don’t have to remove 14 bolts every 15000 miles to change the fluid. And they’re not designed to break on purpose.

[@duggydo]

I wish more manufacturers were as smart and diligent as Mr. Banks.

[@jaydunbar7538]

They are, they just focus on different customers. Banks focuses on customers who are willing to pay for quality R&D and aren't afraid of doing their own research. That leaves millions of available customers who just want something not stock that still want a product to buy.

[@CTrane82]

He really sold me when he called them “Ass Hats”.

[@westtexastll1978]

@ Banks Power If one actually takes Gale's statement literally, that what those "flat-back" diff covers LITERALLY are: "ass-hats". 🤭🤣😂 (He just didn't say, "pun intended"... 🤣)

[@chrisweivoda9592]

It's great how he calls them asshats, saying extra fluid is bad and doesn't help with cooling, and then proves himself wrong when the aftermarket cover with the extra turbulence runs 28 degrees cooler than a stock cover and fluid amount in his test, proving the extra 3.5 quarts of fluid is helping cool by overcoming the extra turbulence and still running 28 degrees cooler. Classic 😎

[@charltonf250]

@@chrisweivoda9592 So double the amount of oil you pay for to make up for shitty design?

[@chrisweivoda9592]

That's not what I said at all. My point was he's saying extra fluid doesn't help cooling, then proves extra fluid, even with a worse design, runs cooler.

[@jmackinjersey1]

I can honestly say that after watching that entire video, I am extremely impressed, and that says a lot. If you have taken that much time and energy to make something as simple as a rear diff cover even better than the one from the factory, and better than pretty much anything else on the aftermarket line up, I am pretty sure that the mainstay products you originally made are just as impressive. I have been around cars, trucks and heavy equipment for more than 90% of my life, and I have heard of Banks equipment for a long time. But I haven't really gone too far into the aftermarket or hot rod section of the diesel industry. My experience with diesel is extensive, but mostly just for repair. I keep the gas side for the hot rodding. But now that I am in the market for a new 2500 series truck and pretty much getting the diesel engine option, I am definitely putting Banks on my list of improvement, aftermarket parts. Thank you for all you do.

Heavy duty axles don't have humps around the ring gear and have done fine for 50+ years.

Nice to see the idea come to something! I appreciated that he addressed the concern I had when I saw the scoops. Took more to break it than I expected. Probably won't be an issue on a tow vehicle like it would on an off-roader, though I would worry about someone putting a floor jack under it. Still, very nice piece and great to see the engineering behind it instead of the ad wank you generally see in commercials.

[@Alpejohn]

Wow.. This was very impressing! I LOVE when people making parts and go all in to make them better in EVERY possible way. This is not an upgrade, its several upgrades in one package! Extensive testing like fuel economy etc. at this level is really awsome, and i enjoy watching proofe that the parts i buy to upgrade my car (truck) actually WORKS, and is not just for show. Loved the fluid dynamics stuff, did not know that the cover actually was this important. I learnd alot! Thanks! :-)

[@AbbeyRoad69147]

Finally!!!! Fantastic work! Been waiting for this for months. Now I just need you guys to support D44 and D35.

What he said. Us Jeep guys need help real bad!

[@ronaldellis3888]

Mr. Banks I have to say you are one cool guy! I appreciated the video you made about your diff cover and the way you think about design, I sort things out similar to the way as you do. I can really appreciate your quest to answer all the questions of designing a product. Some people might say you overthink things, but I think you are a man of uncommon intelligence and distinction, which is more rare to encounter nowadays. Thank you for being inspired to design and inspiring others in the process. Pease keep up the great work! Ron Ellis

[@crazyperson5222]

This guy Gale Banks is a very important person in this world! Other guys don't do enough research to make efficient and purpose built products, they just make it pretty or make it give u a boost in power with no protection for the motor/transmission, whatever makes them money. Gale Banks makes the money and stands by the product he sells and teaches the world of his products function and the research/tests he does!

[@bgj2940]

Good job guys. Finally some true engineering. You might want to look into racing applications as well. GTR's,Corvettes, Camaro's, mustang's.... Hell even the Miata (the most raced car ever produced)

[@Fluffy65]

That's what I'm thinking too. Where's all of our race and muscle car applications?! Hell, we'll need them for powersports, Jeep, and other popular off-road models too! I think Gale just found the product he can retire on.

[@DesertRunner602]

Never been excited for a diff cover video. I've been waiting for the final product

[@MCMUSICH]

This is how research and great testing works! You guys do an awesome job with everything you make!

[@bankspower]

Thank you! Cheers!

[@tylerbrandt6219]

I'm going to school for diesel automotive and I gotta say, your videos are more informative then anything I've been provided by my school! Thanks for that. When I get my truck it'll be a Banks truck for sure.

[@wheel1775]

Never in my life did I ever expect I’d watch a 30 minute video on a diff cover. However I’m glad I did. I was fascinated by all the research that went into the Banks cover. It’s clear to me that the other guys just bought an off the shelf cover from a foreign supply house and just put their logos on it. Those square covers are easy to make but cause more problems than I ever expected.

[@donbrutcher4501]

I'm an Automotive Engineer. This is the way real engineers go about their work. I am concerned the lube may be being kept too cool. Might not be driving off condensation at these lower temps and the viscosity of the oil might be staying too high for proper lube of the bearings.

[@relyenterprisestx]

Don Brutcher I agree, in low winter temps, cooling may be too much. Running in sub zero temps that ram air may be a problem. As he stated, more fluid takes too long to heat up, the same could be said for his ram air system in cold weather. In his design it may never heat up to temp.

[@westwing23]

it looks like you could plug the holes to prevent air ramming in.

[@relyenterprisestx]

Mike Also, Notice how he’s been bashing the flat cover as worse than factory but then his tests show they keep fluid temps down. Not that I’m a fan of flat covers, but shows bias.

[@westwing23]

@@relyenterprisestx Its abit more complicated than that. Its all about proper flow and getting things into operation temp quickly and keeping it there. The flat covers was causing it to bounce awkwardly and it doesn't cool things down right.

[@bboyda4399]

I think the biggest problem he pointed out with the flat covers was the work(hp loss, heat) being put into the oil.

[@schmitty69]

YESSSS I feel like I've been waiting for this for over a year!! I need this cover for a 2015 Silverado 1500. I want a drain plug, fill plug, and some type of sight glass. I dont care if its 600 bucks. I. WILL. BUY.

[@truckcampertraveler7369]

Jeff Schmit hahahahah

[@jaydunbar7538]

Its not just a feeling, it has been over a year lol

I can assure you i will have one of these under my truck! Thanks Mr. Gale!!!!

[@bunkybell1120]

You are the man. I have always wondered about the flat covers. Thank you for taking the time to show us all what's really going on. With these after market covers. Keep doing what your doing. Great video I learned today. The 12 dislikes must be his competition 🤔🤣

[@Fonzieshoots]

Pushing the industry forward! Good on you guys

[@timcahill7792]

God bless u gale banks, thanks for taking the time to correct a issue many people were looking over. True engineer and Craftsman. Also love that u brought up gasket cinch lol my favorite paper gasket dressing. Almost like pvc glue

[@elektro3000]

Hell of a video, I love actually getting the full explanation for everything, including the testing! I listened to you talking to Matt Farah about this, that's why I clicked this video. I'm looking to get a new diesel Ram 1500 soon and tow with it, I think I'm going to put your diff cover on it.

[@cjbales1981]

Fml, FINALLY! Thanks Gale you truly are one of the greatest heroes of all time!

[@larryklusza5773]

This was so entertaining "and" informative! The information was presented in a way that made the science fun as well as easy to understand. I almost want to buy one. But then I'd have to buy a truck to put it on. On the other hand, if you happen to make one for a '70 GTO 8.2 inch 10 bolt - I'm your man! Great job!

[@DragonsTaco]

This was a fantastic presentation, thanks so much for sharing this! I have a Toyota and had some jealousy that the other guys had back covers and mine was integrated in the housing. I can say I'm not jealous anymore!

[@stephanM5]

Gail you're an absolute genius! Love the research you do.

[@kushkiller7108]

Awesome. I dont even have a vehicle that this could work on but I want one.

[@TH3C001]

Good god, I love this, I love this man, I love everything about this video, I love the extent they went to research and design something that's seems as simple as a cover to create the perfect one. This cover is exactly the one I would make if I had the appropriate tools, time, and materials. It makes sense in every way that makes the competitors look as though they were hatched from the minds of knuckle staggers lol from proper fluid flow to adequate surface area to direction of air flow Banks has the perfect common sense design that simply works. It's an absolute work of art and I'd love one for my own truck even though I never tow and the only thing I haul from time to time is ass lol. If this is what this man can do for diff covers then I know right away the rest of his products are the real deal.

[@parkerm6651]

I'm graduating with a degree in chemical engineering and the fluid dynamics behind this were very interesting and informative. Thank you. If you ever need an engineer I'm available.

[@blendpinexus1416]

a good experienced engineer's intuition is indespensable. banks took one good look at the other diff covers and he just knew something wasn't right.

[@TheAlane0607]

You’ve perfected the diff cover, now what can you do with a transmission pan?🧐

[@702muzik]

I'm waiting on that lol I hope he does

[@glasser2819]

A centrifugal filter (spin the oil) would easily remove all the contaminants in suspension! Cheap Honda CB125 motorcycle use to have a "centrifugal filter" to catch the internal clutch particles out of engine oil. Cheap and simple design! 👍🏼
