Look at that baby ! according to PUTC it comes with the max tow package. Will this fit the 11.5 AAM in my '05 ?

That is nice...

 

I'd like to know if it is would fit too. Although it would be dealer only and that means even more rediculiously priced than the Mag-Tec products.

 

It does not even have a drain plug.

 

Should fit, the Axle housing is unchanged...

Thou being a MOPAR part it's probably more money than a Mag Hytec.

 

I want that!

 

Wow, that is nice. I can only imagine the price. Up here, I'm not to concerned about my diffs heating. Our average temperature for the year is a balmy 35.6 degrees.

 

X2. No reason it shouldn't fit. I bet Mopar will wan't at least five big bills for it. Supposedly the capacity is increased, but it sure as in heck doesn't look like it.

 

Why would anyone want this over a Mag Tech? This has no additional fluid capacity which means that at most, maybe 2 degrees cooler. Sounds useless.

 

How do you know it doesn't have additional capacity, and where would you get a small number like 2*? Have you tested this cover?

The finning and aluminum construction will provide a lot better cooling than the non-finned steel cover, no real way to dispute that.

Is it better than the MH, doubtul.. but for stock its pretty good!

 

NOT WANTING TO ARGUE, but, I have personally been involved in various amounts of metallic testing throughout my career in the Aviation community. I can say that the difference in heat dissipation of Steel and Aluminum differ depending on the actual grade of metals, thickness, and inert cooling capabilities. The fact that this thing has cooling fins is, quite frankly, not a huge factor in cooling as much as the type/grade of aluminum used to construct it. I can guarantee that this will be a cast piece, thus limiting the amount of heat disipation. Plus, if it was an extremely high grade of machined aluminum it would cost a fortune.

As far as fluid capacity, I am judging by the photo. The cooling fins are flush to the actual case which means that it should only hold as much fluid as a stock one.

IN CLOSURE, I agree, it is definately better looking than stock. Kinda makes me think of the rear diff cover on a Nissan Titan

 

They put the rear diff cover on Nissan Titans due to issues with blown rear ends because of heat.... They must have done test to ensure the part worked and was designed properly.

 

I don't think they would do it for looks!

 

It looks cool, but I wonder just how much air can get to it since it's behind the diff. Also, if in muddy/dirt situations I would think the area between fins would collect buildup and that would eliminate much heat dissipation. I guess I'll just stick with my old stock cover. Towed a lot in ambient temps over 104 and never had a rear end problem, yet.

 

I don't want to know what kind of dirt and mud your driving thru. I have had a MH cover for over 40K miles and its never been dirty, plugged, or covered in mud and I have done a lot of backroad, muddy driving.

I think you would be surprised how much air gets back there.

It won't take long after it hits the system for someone to buy one and report on the different temps from it.
