Why not just run the factory cover with the Carli bash guard?
There is no evidence to suggest that a larger cover helps improve anything.
Gale banks recently did a video on it and is currently researching data to see if larger covers actually help.

I already have the Carli front diff guard. I am looking for a diff cover for the rear that isn't thin metal. Not looking for a larger capacity one at all, just armor.

Purple Cranium makes two diff cover protectors, a full cover and a half cover. I run the half cover, heavy duty quality stuff.

The rear should be a 11.5 not a 11.8, Just have to make sure if you have the rear sway bar there is clearance for the sway bar on the cover.
If you move to 4.30 gears your 11.5 BECOMES an 11.8 as that is the only ring gear diameter that ratio comes in. Just FYI.

That I did not know, I only found like 2 manufactures that even make 4.30 gears for the AAM 11.5 lol.

Well kind of. You have to install a conversion bearing (included in the kit) to make the 11.8 gear fit. I think there are other differences between the two axles but not sure what they are.
Also, I have had time to put some miles on them now and I am beyond happy. "The Rear End Shop" in Livermore did an amazing job getting these set. They are dead quiet.

Nice. I currently have 4.10 with 37x13.5x17 Cooper STT Pros and a 48RE 4 speed, I am up in the air on if the price of 4.30s is worth it or not. Nitro is the only ones I know that make 4.30s for both the AAM 9.5 and 11.5, well at least that I have found so far.

Nitro ring gear for the 4:30 gears is 11.8 not 11.5, it fits in both axles. If you run any other gear sets they are 11.5,if you have an 11.8 ring gear and run 11.5 gears you convert it down to 11.5. The 11.8 rear axle runs 300 mm shafts also.
I was told by the dealer and by nitro that all Aisin trucks have the 11.8 rear axle, when I tore the rear end apart it did not have 300 mm shafts so I have the 11.5. I used their kit for the 11.8 rear end and have to swap out 2 seals.
The conversion bearing is for 11.8 axles running 11.5 gear sets only.

No pictures for this update, but just got 4.30's put in. Really woke the truck up.
Fun Fact: the rear AEV cover doesn't fit with 4.30's
Wait, the AEV Prospector XL is running 4:30 with the cover?

All you have to do is shave the 4.30 ring gear. Takes about 20 minutes once the cover is off.
