Dana 44 Dynatrac Prorock Diff Cover

It's a no nonsense, purely functional diff cover. I'm sure the welds could be better for a cost. My corner welds are far worse.
Has anyone been following the Banks Power series on diff covers? There is an interesting argument for a stock style cover beyond our clearance concerns.
I do. Really interesting. At least for me it is.
Like the one they use the clear diff cover.
Have you see that one yet?
There are at least 4 videos on the topic and maybe more to come. The see through covers are nice. I never thought about the importance of smooth transitions around the ring gear, but it makes sense.

$100+ is kind of crazy for a cheap factory Dana cover. Im sure it does it’s job. The stock GM 14 bolt cover has played in the rocks one too many times. Not sure how much longer it will last.
It would be nice if some manufacturers actually posted drawings with posted dimensions for us TJ guys. I got Ballistic Fab to add them a few months ago in another forum thread.

They are built specifically for the TJ/LJ Rubicon and built to clear the track bars and steering components. But at $189 it aint cheap.
The Solid Axle Ind covers are prob the best bang for the buck at $65. Thats really hard to beat.

Im pretty sure the ProRock housing cover is proprietary. As the ProRock 44 housing is vastly different than a standard Gen 1 Dana 44.
The Barnett? It does exactly what it needs to do and nothing else.
The overall dims aren't all that useful. They don't tell you if the critical parts of the upper portion will clear. However, I do think that silly skull would interfere with my steering. That is the beauty of the Barnett. We know that the upper half of the stock cover will clear, so they left it alone. All the armor is located where it needs to be.
Solid is well documented to not clear the track bar without a lot of bump stop extension. I know a guy who cut his up into a SOLI cover to make it work.
So why charge so much for it then? Just for thought. Not looking for an argument bc I generally agree with the Barnett cover form and function.
Im confident in their ability to engineer and build the Dana 44 cover to support the TJ/LJ known clearance issues. BF doesnt come up short in their product department. Im with you on the silly skulls. Wish more brands would offer unbranded items. Id pay more.
Solid 30 or 44?
I've been looking at the Metalcloak cover. Looks basic and effective. Good price as well.

Specifically a Dana 30, but I don't see where the Dana 44 front would be any different. The SOLID logo is huge and a big chunk needed to be cut off and plated shut.
If T&J is selling the Barnett for ~$119 or a bit more from JEGS/Summit, then it is less than many of the more extravagant and problematic covers.

I haven’t watched all these videos yet, but it got me thinking about what happens when you rotate the pinion. If you do that and then fill your diff the overall fluid level is going to be lower/less. It seems to me you should compensate for this in some way, by lifting the Jeep when filling in order to get the proper amount. But no matter what, when you put it back on the ground, say with a rear Dana 44, there is going to be more fluid at the ring gear and less at the pinion. I’m not sure how much effect that would have, but it would seem to starve the pinion and flood the ring.
Ok Dad. I finished school today.
So, is there a 4th video with the results or are we still waiting for that? The main idea is that the stock cover and fill level are designed to maintain a specific viscosity while properly lubricating the ring and pinion and bearings. When we screw with that by changing the diff cover or rotating the pinion, we compromise the lubricant and gears to some extent. My thinking is that changing the diff cover would be a greater compromise than rotating the pinion. But both would be a compromise. There doesn’t seem to be any way I can think of to ameliorate the compromise. :tiburon:
Since you might be hard pressed to find a barnett. Rock Hard 4x4 makes something similar to the barnett cover.

I have it for my Dana 30. It’s very thick and heavy. The metalcloak trackbar clears on my Jeep with the front shocks at full compression.
If I were to do it over again (and I still may) I would get the Barnett style. I had a MC gift certificate so it was free.
MC positives:
Heavy duty
Low enough profile to clear my trackbar
Has lower drain plug
MC negatives:
They raised the fill plug which puts it directly in line with the tie rod
You have be conscious of how much fluid you fill it with because of that raised fill plug
