    We don't have the result yet, but the theory is that when you change the cover you change the design lubricant capacity and this could cause more harm than good. Can't wait for part 2.

    Sounds like a good test. never been done before. but you dont have to over fill them. and what i like about them is the drain plug. and not having to open up the diff to change to oil.

    Interesting, looking forward to the results. I also like the convenience of draining and refilling with the covers.

    I'm gonna have to follow this. I had NO idea about overfill or even the high temp the rear end runs at. Very interesting!

    I see how overfill & underfill would affect temp but not extended capacity.
    Aluminum cover will dissipate heat faster than steel also, think of heat sinks, they are not made of steel.

    No matter what the findings I’m still going to purchase & install the PML design.
    Only 1/2qt more the Stock & the inside Shell is similar to stock design so refill will be right @ 4qts.

    I’m mainly installing a new cover for the drain plug which makes for fast mess free service.
    30 min tops & my AAM 11.5” is ready for the towing season.

    It’s ridiculous AAM didn’t install a drain plug into the Differential Itself like ZF did with the 1500s.

    Mr Banks is really thinking outside the Box! I really like it!

    It sounds like his biggest concern is fluid level. He keeps referencing drowning the gear in fluid.

    Im more curious at the motives of these tests. For what purpose are they trying to prove?

    I do find it interesting that both in the video and on their website they go after aFe as a competitor.

    Regardless Banks makes some amazing aftermarket pieces for the diesel market.

    I'm definitely intrigued to see what the outcome will be.

    I dont understand how adding more fluid at the correct level would raise temps. I can see how overfilling or under filling could.

    the level when parked and running is different. adding more fluid even if at the same level parked might give a different level while running since the flow in the diff is different
