Mag Hytec Diff Cover

[chri5k]

I respect Banks, but I did not see anything definitive in his videos. Just a lot of talk about working the fluid and flat back covers. What about the difference in temperature between the OEM and the aftermarket covers? That would be easy to test and report on, you don't even have to put lights in the differential. Where's the data? Seems like a lot of hype to me. I appreciate that their cover has a great design and will probably aid in cooling the oil, but they do not make one for the 1500's so I had to get something else. I like the looks of my differential cover and expect it to last a long time. We do a lot to our trucks for aesthetics.

Part of Banks findings was that there is an air flow dead spot behind the diff cover so fins behind the cover have very little effect. Banks design catches air from the lower sides of the diff cover and pushes up between the fins to aid cooling. The data for this and the accompanying heat reduction information is on the product page.

The MagHytec cover for the 1500s is pretty rounded on the inside. The HD ones are much more square backed and I honestly would avoid them if you have a HD truck.

After seeing that banks video I almost pulled mine off and put the stamped steel stock cover back on but since the 1500 version is rounded inside I ended up leaving it. However after seeing those ones @Burla posted I might look into one of those.

Yeah, I appreciate that, and, as I said, it looks like they have a well designed cover, I might have purchased one of theirs if they made one for the 1500. However, they badmouthed several aftermarket covers with their observations, but they never backed up these statements with data (increased temperature due to "working" the oil, or not getting sufficient lubrication to the pinion bearings). My guess is (only a guess) that they measured the oil temperatures with the other covers and either noticed no increase in temperature (due to "working" the fluid), or noticed that they did, in fact, help keep the differential oil cooler. So they chose not to report those findings (again, only a guess).

Pretty well every light duty diff cover or back of the diff from any manufacture'r is shaped the same way ,and none are squared off like the majority of the aftermarket covers are.That in itself should tell you something.

Yeah, it's cheaper to make them round instead of square... In jest only! I expect that the round cover is an efficient design.

The factories had diff covers figured out by the 50's,lol. If it ain't broke don't fix fix it,lol.I think you'd be hard pressed to find a factory diff or cover that looks like a Magtec cover.Just maybe the engineers who designed the diffs might actually know a thing or 2 about fluid flow and fluid shear in the diffs. You'll notice even the front diffs and their covers if they use a cover are basically the same design and shape as the rear diffs from the factory.I'm kind of leaning towards the factories engineers knowing a wee bit at times,lol

I’m kinda liking the B&M cover the Burla posted. I checked it out on the Holley website. Very round, at least more so than a lot of the others. I might go that route.

I have seen a few covers that are not shaped like the one thats on the Rams.
My 12 bolt in my Nova did not have any type of channel in it just to name one.
Not saying its not a bad idea for the channel in the cover but I think the gears pull the oil back to the front.
I like the fact on the 1500 it adds more fliud and the aluminum should dissipate heat better and it looks purtty. lol gotta have purtty.

Look closer,that channel at the top guides fluid from the crown gear over to the axle side bearings on a 12 bolt

 

[69GWC]

Yes but its not that same channel like our truck has, its what I was getting at.

Honestly if the stock cover allowed more fluid I might not of even messed with changing it, I just felt like a working truck needed more fluid capacity then what it had.
Changed the one on the car for looks...lol

It does the same basic thing,guides fluid to where the manufacture'r figures fluid is needed.

I'm not saying banks is the best, but research and talk to some guys. I would chat with @Hemi395, he has done a lot of research on it and he found all of those youtubes, I think he is even comfortable with the mag hytech.

I wish banks made one for 1500

Banks doesn’t make a cover for the 1500 trucks




Mag Hytec is a great cover and yes there is plenty of clearance to install after the Hellwig

Good job on the detail work under there.

I just wish the banks had one for the 1500. I don't tow a rediculous amount but I do have a 24 ft pontoon with a 150, and a 18 ft utility trailer I use about once a month. I'm sure that puts a strain on the rear end. My main thing it I want a fill and drain port so changing the oil isn't such a pain in the ass. After watching those Banks videos I'm not sure I want increased capacity, just increased cooling.

I've watched the Banks videos. First, Banks is quite the salesman and self promoter. Second, mag hytec has been around forever, I've never heard of one causing a rear end failure.

Yes he is definitely a good salesman, it does make a lot of sense what he was saying though. He also stated that the mag hytec did outperform the stock cover. I just don't know if I want to spend that much on just marginal gains..... Who am I kidding I'm sure I will, I would just prefer the Banks. I wish there was more info on the B&M, it is rounded and has more capacity. I'm kind of leaning that direction.
