Got it in today
Thanks for the torque specs, mine didn't come with instructions.
Easy install, oem gasket worked great.
Took more like 4.5 bags to fill it.
Fits no problem with the Hellwig sway bar.

Sure I'll install it. I already bought the gasket and oil.
What do you guys think about using some sort of epoxy based paint or high temp paint instead of sending it out to be powder coated? I know a lot of guys like to paint their rifles with various high temp spray paint. Not sure how well it will work on a diff cover and how long it would last but????
So I just did mine on my '24. I was going to do it last weekend but I saw that PPE revised their instructions earlier this month and now show that it takes 5.3 quarts if you have 3.55 gears so I had to pick up another quart over the week. I was able to get in somewhere between 5.2 and 5.3 quarts until it was full from the factory fill plug. Interestingly, using the PPE fill plug, it was full right at 5 quarts but when I pulled the factory plug, nothing came out so I added more until it did. I just passed 10k miles and my oil was pretty clean and I didn't see anything of concern inside, which was nice.
Thanks for posting up your fill capacity and PPE change of instructions. I just looked at their instructions and they are for sure different from when I ordered mine back in November. Previous version stated to follow factory fill capacity new version gives quantity- big difference.
Based on the instructions the PPE cover adds 1.3qt more fluid volume to the factory fill. Thats noticeable difference in additional oil capacity compared to the stated fill capacity (4.02 qts 3.31-3.55-3.73 [] 4.12 qts 4.30) found in the Ford Service Manual (as of 4/2024).
I've been covered up with projects and hadn't any time to install my cover yet. I originally ordered 5qts looks like I'll be needing another. There was some discussion if the cover and fill plug design was based on the early models ( Pre February 2023 production dates)
Based on your experience it suggests that the PPE fill plug is not at the "optimal" height for the revised February 2023 and beyond production date fill capacity. I actually called PPE when I ordered my cover and asked them this question about the fill plug location last month and was told otherwise.
Do you mind confirming the right cover gasket part number you bought is PC3Z- 4036-A? When I looked up the part number I got three different gaskets listed that mention they fit my truck. One was about $16 msrp the other $56 msrp- I added my vin to the parts look up and both say they fit.

The gasket is PC3Z-4036-A. I suspect they put their fill port at the height of the lower and incorrect factory fill port because their instructions mention that you may need to fill using the ELD connector port. If it was in the correct location, you wouldn't ever need to use the ELD connector because you would just use the fill port they put in there...Thanks for posting up your fill capacity and PPE change of instructions.

I also believe it is in the wrong spot because it overflowed with 5 quarts with my truck reversed onto my sloped driveway where the fill plug should have been elevated and allowed more in. I mulled over this week how I was going to fill it cause putting in exactly 5.3 quarts is easier then making sure my truck is level but when it was "full" with 5 quarts I had to change my plan. I ended up rechecking the oil level in the street in a level spot and when nothing came out of the factory plug I knew something was up.

Looks like they now offer black covers - didn’t notice those earlier
Thanks for confirming. This is what I suspected might be the case all along. Also part of the reason why I posted a photo of my factory fill plug location earlier in this thread, for comparison sake for others who wanted to check their own.
This is well written advocacy, and Gale Banks is definitely a very smart guy. He knows diesels. I have and love the Banks iDash. Having said that, he and his company also sell lots of snake oil — like CAI (cold air intake) systems and exhaust components that are expensive, flashy, and do nothing good for the trucks they are attached to. The value of slightly cooler air is next to zero on motors with forced induction (like all of our diesels), and the OEM air filters and exhaust systems easily flow all the air needed to optimize combustion and power at or slightly above the factory-programmed fueling rates. They also filter small particulates more effectively and continue to function well even after they have captured a lot of dirt, yet CAI systems continue to be among the most popular early modifications. CAI systems are expensive snake oil, and Banks knows it, but his company continues to hype and sell the heck out of them. Having seen the research on aftermarket air filter risks and rewards, I’m highly skeptical when I read the Banks sales pitch on differential covers.
Banks is a selling machine. He could probably sell guys a “dual dipstick kit” and a “double overhead glovebox” if he went to his awesome shop and made a sincere-looking video describing the benefits.
Post up your personal ran flow and dyno numbers. What state of the art shop do you work at that has all this testing equipment?
This cover fits a 2024 Tremor with the HO Diesel? I have been looking for one.In case anyone was waiting for the Sterling 11.6 Diff Cover. I kept hounding Banks and they do not intend to make one for the foreseeable future...

Most of the scientific research to which I refer was posted on the Diesel Power and Cummins forums about 17 years ago by an engineer with the screen name “Spicer”. He posted all of the data — initial vacuum reduction, vacuum reduction with increase in filter load, and maximum particulate size pass-through. It included several pages of charts and graphs that ultimately proved consistent with the experience of forum participants like my brother and me. I’ve tried to find the original Spicer document twice without success, but here’s a link to my experience, description, and rationale. Some components of this are thoroughly understood — like the relative air density effect of forced induction and reduced air temperature. As every pilot will attest, ambient temperature has a profound impact on the horsepower of naturally aspirated engines, but a slight temperature swing is all but irrelevant on turbocharged motors.
I’m not here to discourage you from buying any of this stuff, including dual dipsticks if that’s what you’re moved to do. As I said in the posted link, I continue to make stupid purchases myself.
Cold Air Intake Rant
I think you're overthinking this a little too much. A lot of these simple to upgrade parts are like jewelry to us men ( nothing against any women in this group
). At the very least, we want the part we're upgrading to offer some type of benefit over the factory part it's replacing. Whether that's to look better, perform better, or to simply help ease with maintenance.While I agree a aftermarket CAI provides little benefit to a stock truck, I also understand there's a lot of trucks out there that are no longer in stock form. It's not Bank's responsibility to vet a purchase. He compares his unit to stock and other competitors on the market. It's up to us to decide if upgrading is beneficial or not. The last thing I will ever do is question an entire company when they offer an item that doesn't offer me personally any benefit.
I agree, mostly. Mr. Banks job is to make money, not protect us from wasting ours.I think you're overthinking this a little too much. A lot of these simple to upgrade parts are like jewelry to us men ( nothing against any women in this group

Part of my passion and over-analysis comes from feeling foolish about buying all the CAI intake claims which, in hindsight, were so profoundly improbable. When I saw how much fuel I’d have to flow to need more air I felt even dumber.
The other part is some CAI kits actually have the potential of damaging the trucks they are attached to (by failing to filter out harmful particulates). I don’t recall the Banks CAI being among those used to deny warranty claims, but others marketed using the same “improved air flow” claims were.
You’re right about people buying jewelry for their vehicles, of course, I’m plenty guilty of that myself. Each to his own. Heck, I see home-made spoilers on gutless Honda Accords that probably can’t reach speeds where the spoiler would be of use. I’m just trying to save others from making the same stupid mistakes my brother and I made.
