That's why I love Gale Banks. Always wanting to learn and teach. Not afraid to share his designs. 👍👍👍
and not afraid to click bait a title and waste everyone time...
Matt Lane you have to know about mechanics and a little bit about vehicles to understand this isn't clickbait. Sorry bud, don't diss someone just cause you missed the points

"Do Diff Covers Work or Are They Just Bling?"
Did we get ANY answer at all... NOPE...
We got a old geezer that talked in circles for 10 min.
I came here to...... find out "Do Diff Covers Work or Are They Just Bling?"
Click bait... if the title was "how diff covers work" I WOULD NEVER HAVE CLICKED...
how do you figure? you didnt know this already
Bloody interesting listen8ng to a man with natural passion for mechanical learn8ng and resulting knowledge
allistairc123 you using a samsung phone?
Well if he was using an iPhone listening would be spelled correctly, so my guess is yes.
Maybe on a pc keyboard seeing that the 8 is near the i.
Apple keyboards are the same ... perhaps you mean 'qwerty'?
Didn’t have an Apple in front of me, so other than a phone key pad.
I love the fact that he is just as honest as can be and not sugar coating shit
The man is a genius period. I wish I knew just half of what he's forgot.
Amen to that.
right on
More like he's working to the scientific method ie remove as many variables as you can and test in a repeatable manner. He's right on one key thing, no one or few do real tests on their products to prove they really are good or better.
Good thought - BUT being an engineer... he wrote it all down.
Thanks for always holding the automotive industry accountable!
I am really looking forward to the follow up video to this!
It is always a joy to listen to someone that is so knowledgable and passionate about their craft.

Hell Gale Banks for president!!!!!!!!!!!!
Go Banks! Scientist, old school. Respect!!
I like my new cover because it has a drain plug which makes it easier to drain, it has a dip stick to check level and it holds more fluid. It also has a port to stick a temperature gauge in.
Glad he's deciding to pose the question and subsequently come up with an answer, I'll be paying attention because I've been teetering on whether or not to buy diff covers and trans pan for my 02 7.3. Keep it up G!
Gabriel Mesina 7.3 is the best ford built. I wish they’d build it again and soon because I won’t buy a current ford diesel.
I bought some mag tech cover’s for my 95 dodge ram 3500 5 speed trans. for several reasons 1-drain and refill made simple 2-The covers have O-rings no sealant or gaskets needed 3- The covers also come with magnets for collecting metal particles 4- The covers are deeper so my capacity went up over a quart in the rear but still retaining factory fill level 5- oil does run cooler by about 70 degrees Fahrenheit on average. they look a hell of a lot better than the steel caps that came on the truck. and those are the reasons why i purchased mine. i pull heavy commercial air conditioners and sometimes pallets of sod a few years back i installed the complete banks power pack system With the ram air intake kit along with the banks double shot water methanol injection system which is working out pretty awesome so far. i easily doubled my power output. and because of that my next concern was my drivetrain and keeping it all in one pice. i am curious to see what the test’s say.
I'm with you, I've had banks' stuff on my 2002 cummins for 100k...flawless performance. Bought a twin turbo kit for an old small block I had too...can't say as much for that, but had a hell of a lot of fun with it ;) Sold to the next guy and he's still out there boosting away.
speed demon - I'm confident that you did all due dilligence in before and after temperature testing.
i’ve been using my old truck for a long time for hauling. and the newer trucks were starting to kick my ass they could get the job done faster. and when your truck only goes 72 mph flat out that starts to become a problem in the hauling business.I usually did about 52 to 55 mph so I wasn’t beating it. just made for a long day. so i went from a 4.10 to a 3.73 to get a little more top end and once I did that the measly 180 HP had to be addressed with a complete banks kit. and that did the trick there was a few times I noticed that I could smell hot gear oil when loaded on a hot day. and taking a commonsense approach i figured because went with a taller gear ratio and added power there’s going to be more heat generated.That’s when I started checking there rear axle temp. By climbing on under the truck with a infrared temp gun after a heavy pull. that’s when I decided to bite the bullet and spend the small fortune on front and rear diff covers. there’s no doubt they help keep the gears cooler in my application. Would it be worth it to the average Joe that hardly pulls anything probably not. maybe if your running 38’s with the stock gearing. ive seen lots of newer trucks like dodge With louvered aluminum diff covers from the factory even my wife’s 1989 Toyota supra turbo has a louvered aluminum diff cover from the factory. So there’s gotta be something more to it that the engineers American and Japanese see as a benefit to having Louvered aluminum diff covers other than just bling.
70 Degrees ?! That's Great !!
In road-race applications, a pump and seperate oil cooler is frequently used on differentials.
And THIS is why I only use Banks products on my 2003- 7.3 F350!! You guys have always been and always will be top notch industry leaders!!! I'm looking forward to the follow-up of this video and if you do end up developing this diff cover I will undoubtably buy one from you! I cannot speak highly enough of Banks and what they have done for my truck. I pull a 6 horse trailer with six hanoverians all over the east coast in the summer time for horse shows. I can honestly say that my Bank's system has never let me down when it comes to rock steady reliable performance!!! Thank you guys for all that you do!!
Do trans pans next please!!!
SIIN MC Makes sense because the pan is under the guts of the trans, could touch the ground and wouldn't make a difference in terms of trans performance
Depending on the results of the diff cover results, it might be worth looking at. The air flow is different between a trans pan and a diff cover. The trans pan is at least directly in contact with the air flow, where the diff cover is not.
Yes, the way a rear axle gears work versus the way a trans work is apples to oranges. BUT, all I wanted to know by saying to do trans pans next is just the same reason Mr. Banks is doing this test. Do aftermarket “cooling” pans actually work. That’s all.
deep cooling pans do work, even the thick aluminum transfers the heat faster that painted sheetmetal, gets it farther down into the airstream under the truck/car, and adds capacity.
The gears in an auto aren't running in oil bath like a manual trans or axle, so the extra capacity isnt an issue as long as its not over the factory level up in the case.
the added capacity increases warmup time but increases the thermal capacity, basically you can abuse the fluid more before it starts to see thermal runaway.
downshifter4179 - You can make a ten minute video about that question too, and waste thousands of viewer's time just like Mr. Banks did.

Hey it works, why make a big deal and make some crazy fiberglass setup?
All it would do is be pretty.
Glad to see even Gale still knows when to hillfolk it !!

Daves Racing Channel done :)
They work pretty good at holding the fluid in. Thats about it. The only reason i would put an aftermarket on on would be hold more fluid, and have a drain plug and sightglass to monitor fluid quality amd contamination, especialy on a off road rig where water intrusion may be an issue.
In my mind this kind of goes without saying but, Gail Banks IS THE MAN! This illustrates why anything Banks Power produces is so superior. There is no guessing just testing. It either is supported by hard data or it is scraped or refined till it does. He is not reluctant to do what is necessary to get the data he needs. Hats off to you sir. Keep up the great work.
Don't we all wish we could leave this world a legend. Awesome dude, hope I can do half of what he has in my lifetime.
I bought mine because of the drain and fill plugs. It's a PITA dealing with the gasket every time you change the oil. Also, the one I had included a port for a temperature sensor. Can't monitor temp without that.
All I know is that when I replaced the stock diff cover on my 1990 Dodge Cummins 12-valve with the Mag-Hytec, it was like new life for the truck. The old oil (even though it was running fine with friction modifier for a rear-wheel locker) was really bad.
I now have a differential full of clean synthetic gear oil that can be drained from its bottom, with a magnetic dipstick that is constantly removing any metal from the oil (as I noticed, checking the level after the first drive with it, and again later when adding friction modifier for the rear-wheel locker).
And, the inside of the Mag-Hytec cover for the Dana 70 rear end is nowhere near as squared-off as the ones that Gale here shows for the newer, bigger rear ends. It also sticks out farther away from the gear wheels.
Granted, if Banks made a diff cover for the Dana 70, I probably would have bought one.
Totally subscribed to see the results of this. I had to rebuild the rear in my old Suburban so i put in a 4.10 and an Eaton Truetrac. So I splurged and put an aluminum cover in it thinking i was protecting my hard work.
I've towed a camper a few times with it and it did well. Felt hot to the touch but not searing hot. Gear Oil stays clean, not burnt.
I am following this, one I just wanted it for bling but if it hurts my truck screw that a can a spray paint will suffice
Consider deflection of the diff housing as well. One of the claims I've heard is that these after market covers increase housing stiffness.
AAM makes a stock upgrade diff cover that is the same capacity just made of aluminum with fins on it. Wonder how that stacks up to a standard cover and high capacity aftermarket cover??
Smart curious man. Wish our next generation could be like him.
With university "science" professors all too happy to exist in their echo chambers and punish opinions / conclusions that differ from their own with bad marks it is highly unlikely. I think you will find university professors are more interested in securing funding for their next research project and getting nominated for some award than they are science, truth or their students. University professors are not exempt from selfishness and egos.
When I first seen the little fan the "anemometer" I thought it was some kind of air cooler for the aftermarket diff. cover and I thought how stupid! LOL!
THIS is why I love this company, and I'll be going with their products on my LBZ.
THIS is why you guys are leading the aftermarket auto industry!!! because you actually put in the time and effort to make sure that your products are the best in the industry
Looking forward to watching the rest of the videos in this series.
If Banks takes this much thought with their products, then I definitely know what company I'm ordering parts from on my next truck.
Only reason i run them is for off-roading. You land your rear end on a rock and the stamped steel cover peels off the diff enough to start leaking. The aluminum one took a few hits but eventually started cracking. Ended up with one made locally from thick steel plate
Hey Gale,Your are a scientist and a leader. Very cool of you to take the time to examine this product application. You are a myth buster.Thanks for taking the time an dedicating your scientific approach.
Ask the question and then guarantees a legit science based answer. Gotta love it!
They are necessary in off-road situations because some brands provide way more protection than stock covers. For example ARB versus standard jeep differential covers
I could listen to Gale all day.
Very interesting so far.
I did some testing on this years ago but not to this controllable degree. The only thing I could monitor was diff oil temp but I didn't have a rolling road. I tried to equalized the load and the driving routine, as well as doing the testing at roughly the same ambient temp and using the same lubricant. Best I could do in the field.
In my case, the cover reduced the peak oil temp 15-20 degrees, but my peak was nowhere near what Mr. Banks was seeing as I could not apply a constant heavy load. I spoke with engineers at Dana and Meritor about these covers and they were generally not in favor. The main objection was that the distance between the cover and the ring gear is part of their calculations with regards to lube flow, aeration (more of which oxidizes the lubricant more rapidly), etc. They didn't like that they increased that distance and predicted negative effects. They had no problems with increased capacity, but they warned against increasing the level as Mr. Banks mentioned. The manufacturer of the cover I used wanted the lubricant level increased from stock. I tried it at their suggested level and then at the stock level but my test equipment could not uncover any differences beyond a margin of error. Still, I left it at the reduced level as my "instinct" drove me that way.
The level indicators were very interesting here and the way the levels dropped. This was an aspect I had not considered. I wonder where that oil is going? Down the tubes? Clinging to the ring gear and carrier? Both? Interestingly, the manufacturer of my cover stated the reason for the increased levels was to feed more oil to the wheel bearings. Laudable, perhaps, but if the ring gear is already doing it, why is raising the level necessary?
I have been running diff temp gauges in my trucks for 20 years or so and there are a great many good reasons to do so, especially if you tow. Even if you don't tow, it can help you choose the most efficient lubricant and viscosity to eliminate drag and potentially increase fuel economy. The diff is a place where the right lubricant can add a noticeable mpg gain.
One quandary I had was placement of the sensor. I note Mr. Banks had the sensors in the bottom measuring the bulk oil temp. Did that too, but also put one up to measure the temp of the oil being spun off the ring gear, which was hotter oil. I wonder if there was any logic or testing applied to the determining locations of the sensors in this case?
Anyway, this is an awesome test and I am dying to see the results!
I've noticed some of the newer HO Cummins trucks have the finned aluminum heatsink diff cover on them from the factory, So I guess that part of it must do something of OEM's wouldn't be using them.
When it comes to overfilling the rear end, if you notice in this video when they show a diagram of fluid level stationary vs 60 mph, the stationary level is right at the fill plug. Which reinforces the old idea of adding fluid until it begins to trickle out of the fill hole. The AFE cover they have on that Dodge doesn't have the same fill plug so overfilling could certainly be an issue there.
Now providing you can fill it to the same level with the new cover, the new cover would probably allow for more fluid capacity, maybe just half a quart or so but more none the less. Overall a higher fluid capacity won't keep temperatures down but it will take longer for the fluid to reach full temp. Also a benefit of an aftermarket cover would be the drain plug it adds to the rear end so you don't have to remove the cover anymore to change the fluid.
Thank you so much for the info Gale. Out of all the big, sell out, big names, like Carrol Shelby, John Hennessy, ect, you always remain the most humble and honest. Thank you
You sold me when you said "ass end." ( 4:17 ) Wonderful video!
This is a great example of what makes Gale Banks a leader. Very much an attention to detail man that only deals in facts. Looking forward to the results of this testing. I think it would also be interesting to see what if any advantage there is to adding a differential cover that has an external cooler and pump assembly.
Just did my miatas diff fluid today. Not sure if I over filled it. It said it needed just over a quart. The results you provide could apply to my car. Excited to see the results!
Finally! A test of these covers and I hope you also do a similar test of the "cooling" trans pans. I have been harping for years that these do not do what they claim and a friend of mine years ago who had gauges on every part of his Jeep J20 proved it out with his diff temps. Thank you Mr. Banks no matter how it turns out!
Different covers come from 4wding, might not mean much in the usa seeing as there's next to bugger all 4wding going on.
Stronger cover doesn't crack hitting rocks etc
Bigger cooling fins to help cool the diff oil
Bigger or easier oil changes or cleaning of the oil
The other is weight changes
Maybe towing on the highway might be good for the bigger fins but depends on what it is and how much
I met Gale in person at SEMA and is knowledge on Diesel motors is outstanding! His products and company are of a high caliber. This guy doesn't B.S.
i been wanting to see someone do this for years i cant wait for the updates
I was just having a conversation with a co-worker after a guy rolled by us with the same diff cover about whether it acts similar to a heat sink or not. Thank you Mr. Banks for testing this I subscribed.
one thing I think a lot of people are missing is that after market diff covers are not only for performance. many stock covers are just thin stamped out metal, after market covers are usually much thicker and will not be damaged as easily which makes them better for off road use.
Looking forward to the results. I have always wondered myself whether these diff covers were a waste of money or not as I have bought them more than once for multiple trucks.
I use them to keep from sticking a rock through my differential cover. I also like they carry a lot more fluid so that if I do spring a leak, it gives me enough time to get to the trail head.... that said, I don't consider them a cooling option.
This is going to be very interesting, can't wait. I hope they publish the lubricant used in each axle since we all know lubricants have their idea lubricating temperature.
That's Gale Banks. Always researching for the best. I also wondered if those diff covers were worth putting on. I think the oil is more important (quality) than the cover. Deep trans pans are next.
Mr Banks, you have always been leaps and bounds ahead of others in the diesel market. I had the pleasure of talking to your guys and seeing the twin turbo diesel s-10 run back in the mid 2000's. That truck was so far ahead of its time. Not a single puff of black smoke from startup, to burnout, to finish line all while running in the 7's in the 1/4 mile. You have alot of haters but that's easy to do when your so far ahead of them.
This gentleman has forgotten more valuable tech and info than most engineers know! Listen and learn. Much respect Mr Banks, I have used your products for years and have never been disappointed.
You’re a man amongst boys. I love the details and research.
I lost my sh** when Mr.Banks stated we are going to SCHOOL THESE CATS.... LMAO
I don't care about anything but the ease of changing the fluid. Mag hy tec is the best.
That's what I own too (Mag-HyTec) on both rear Diff and transmission pan. i'm using the BG Diff oil all around and OEM trans fluid. I just drove 1500 miles stopping
no only for fuel and pee breaks and all was good.
Putting ease as the top priority is usually a bad thing.
Iv always read that they add rigidity to the "pumpkin". It's the main point of cast oil pans and rocker covers, they tend to not warp and eventually leak due to their higher comparative rigidity over sheet metal. Though they weigh more. Oh and better heat dissipation.
I'd say no additional heat with overfilling...maybe slight decrease in temp due to axle tubes aiding in heat dissipation...
That's my guess, and I'm sticking to it.😋
Gale Banks has forgot more about automotive and mechanical things than most will ever kmow.
Without thermostatic flow control - as in an engine oil cooler, more volume is not always better. Fascinating!
I use Amsoils 75W-90 in my Ford F-250 super-duty and it lowered my diff temps by nearly 40 degrees.
I just watched your channel for the first time. Its relieving seeing a video without some kids playing loud music with a long intro doing a burn out or something. Subscribed
Different fluid levels could also be specified to accommodate differences in clutch type limited slip units vs. gear lockers, vs open differential used by different manufacturers. Hypothetical example: Wet clutches in a clutch type lsd my prefer more submersion than mechanical lockers.
Can't wait for the results!!!
Great idea for a scientific test... I did the cheap upgrade... I painted my cover when changing fluid. Ha ha
Not a upgrade you just insulated the heat. Yours truly Mr. Banks!!
Awesome, thanks Mr. Banks... eagerly awaiting your findings.
Compared to standard 80 / 90, you can't beat synthetic, and specifically Amsoil, Period! Very educational, well done and enjoyable vid.
Really looking forward to the results of these tests. I just want to see slightly lower temps in my rear housing. I was told the issue I had was due to the fluid temp getting to high. Had a seal blow a few months back, reasoning from dealer was that factory capacity isn’t adequate for the projected and stated limitations of the truck. They told me, should I order a 1 ton cover or one of these aftermarket covers, they would install it and fill to factory level for me. The seal and brake rotors that were damaged were all covered under warranty, but I don’t want to be in there every few months with my truck in their shop for a few days.
You guys are awesome!!!! The attention to detail is why I love banks, not to mention the fact that you guys have always answered my questions to the best of your ability.
This is why Gale Banks is the Best in his Field and all other fields that he choses as his endeaver! Without yet,seeing the results, I can guess the result. Higher capacity, higher heat. So? What's next? Bearing seal failure? Now for a Stupid question? Maybe so, maybe not. Now if you're running an aftermarket diff cover w/higher level of fluid, what if somebody configured a cooler to cool this fluid? Obviously some obstacles like where to install(front grill)? Plus whenever you add extra connections with and for the cooler and lines, you exponentially increase the likelyhood of leaks, ultimately risking the failure of the entire mechanism. In this case, the axle seals, bearings, and finally the diff itself, usually in that order. Both lol and no lol! Any ?'s or comments?
This is a question I have been wondering for a few decades now I suppose... since they first came out. Finally someone is going to do the testing and break it down. Subscribed!
For the Jeep Wranglers... If you are going to offroad. The factory stamp cover will get smashed on the rocks. So the upgraded bomb proof covers are a must.
"We going to be schooling a bunch of those cats."
- Banks
I can't wait for Part II!!!!! I put a G2 Cover on my Super Duty. Just from my experience, it does run slightly cooler than the stock cover.
I remember I was on the line building engines in Moraine, he was there walking around with some fellas. A run of Marine engines, if I remember correctly. Anyway, I was the only one who recognized him. Quite starstruck to see the legend in my vicinity.
Thanks a bunch for all the info. I like it when an expert explains things in details and also has scientific proof to back it up, not just theory, like most people do here on you tube. I will be waiting for the rest of the videos
Great Idea , cant wait until the next one, wish I could go back 30 years , I would be hammering on his door until I got a job there.
Mr Banks, would be so kind and elaborate on the manufacture of the fluid brand you are using in the diff? Id speculate and say Amsoil?
Us Jeep guys get aftermarket covers because the stock ones are thin and can be penetrated by a rock in the front. In the rear, they can be peeled off the sealing surface by being dragged over a rock.
A lil off subject but I know what you mean about that dead area due to the flat surface of the differential cover. I'm a tractor trailer driver an I find that motorist like to drive directly behind my trailer cause it reduces that wind velocity/resistance to non existence for them while driving.
Thanks for the info and time. I own fords do you know any one who dose tests and info like you on ford trucks? I really enjoyed this clip.
Mr. Banks is a very intelligent man, and his passion shows in his approach to all things in automotive performance engineering. His shop is only a few miles from my home, and I have always admired his accomplishments, especially in the Turbo Power systems he and his team have developed for diesel engines. This Man Is A Legend ! ! ! Good Job Gale.
I think that diff covers are popular because the people driving behind you can see it, especially if you have altered the ride height, and they think "oh wow that guy must have a super badass axle in that thing". I think that attention is why you see so many axle covers with obnoxious colors too
I have done some testing on over filling on Dodge/Ram 11.5 With PML, I run 1 QT over full on all My Dodge Rams 2003-13 , I also have temp Gauge installed on all Trucks. In over 278K miles never a problem. I replace My 2003 11.5 at 82K miles , the pinion bearing failed the rest of the unit was like New. I replace the OEM Unit with TrueTrac all new bearing and replaced the R/P gears. Now the Seller of My TrueTrac adamantly told me to TQ the Side Bearings to 150FT LBS, I called again and inquired Why 150FT LBS is more than I usually do at 110FTS I thought was good. I immediately had heat increases ,But again the seller (Big Name Company) said it was normal on the TrueTrac.. Well when I went out to The Rockies Pulling My toy Hauler Temps went to 400F+ and I had to use My connections to fine a shop that I could used to remove the Cover and Check....Yep Wear on the R/P gears and side bearings, So I re-set the R/P Back lash and RE-TQ the Side bearings to 110FT LBS and continue on... After the 2,700 trip and back home I dropped the cover and Replace it all again do to the wear. IMO that extra 1QT saved that Unit until before/after I could return Home... and I was reimbursed for the 1st unit, it was discovered they were Quoting N m-FT LBS That was 9 years ago, I'm still running 1QT over to present on all My AM 11.5s and PMLs.
He knows what he's talking about, still uses "ass end" to describe the flat side of the diff. Love it!
I got them mainly for the drain plug. The bling was nice, though.
🙏 thank you for the teaching ! I’m running AFe cold air intake so far I’m happy with the performance I seen that cover in their catalog but I’m clueless about performance and benefits so thanks again can’t wait for next episode

Daves Racing Channel done !
I LOVE your videos. Keep up the hard work and your product will continue to fly off the shelves. It's all about the data!!!!
I can hardly wait for the test results! Thank You Gale.
Love this kind of intelligent approach to assessing functionality and performance. Looking forward to the test results Mr. Banks.
Interesting you call the diff gears the "ring and pinion" gears where here in Aus we call the diff gears the "crown and pinion" gears, the ring gear here being the starter gear on a flywheel / drive plate.
Gale is a bad ass dude! Always love hearing him talk engineering! Can’t wait for the test, something I’ve always wondered about as well.
Thanks Mr. Banks. I love your enthusiasm. You make great products because of it, and I'm looking forward to these results.

So why not design and come up with a bolt-on air channeller basically a funnel that takes the air which flows around the top and bottom of the differential and forces it to wrap around the backside of the diff for better Cooling?
I ran a larger diff cover on my 06 Ram 2500. It was a Mag Hytec and I was running a temp gauge before and after andit cooled my diff down to 280 degrees when pulling hard in British Columbia mountains from about 360 degrees. I was towing a 36 foot 10000lb trailer and carrying 2 ATV s
And I did it for cooling not economy
I bought a front mag hytec because of the drain plug. Will be interesting to see if it actually lowers temps
I actually wouldn't be interested in temperature. My major question is do these covers help reduce ring gear deflection from housing flex during heavy hauling therefore increasing longevity? Also if it keeps the bearing journals in proper alignment during serious off-road use?
Part 2 please. I have always asked this question in auto tech in high school and never got a real answer if it helps or just for looks.
Where is Part 3? Been waiting to see the data...
Where is part 2
