Mag-Hytec created a designe to fill the cover and axle tube higher than the original fill level. The amount of fluid with the stock over is 9 pints. I bought a BD cover (they tell you it doubles the amount)It increased 1 pint, to 10. Mag-Hytec increases 7 pints. With a total of 16 pints. The fill hole is at the top, with a dip-stick. No other cover maker does that. Adding 1 pint to 9 hardly seems worth it. Adding 7 to 9 does. I talked to several guys that have them. There is no down side to adding that amount of fluid. And there seals have been holding fine.
Great and Reliable Product, Outstanding Quality.

I have purchased Mag-Hytec 3 times in the past for a different trucks that I use to own, including my last 2014 Ram 3500 4x4 6.7L. I have installed this AA14-11.5 also on my previous 2009 GMC Sierra 2500HD and have been very pleased with the quality all over.. No leaks whatsoever in any of these previous installations. so I recommend this product 100%. Now, for the front differential cover the Mag-Hytec I wish the same product would be the same happy ending, but what I heard from many people then the front it does not fit unless you will experience some rubbing from the turning front tie rod. I wish they would have pay more attention and make it fir perfectly without any of this touching problems. I also wish that the Mag-Hytec reduce the price for the returning customers more often..

Did not fit. The tie rod damper plate bolts rubbed against the front of the cover gouging it. Hytech mags solution was to rotate the damper plate 180 degrees away from the cover. Won't wor due to the design of the tie rod. New design needed.

On my 2010 Dually, perfect fit, having a dipstick is great. Adding a diff sensor for temp. Amsoil severe gear oil runs great and dont stink like normal gear oil, a simple but happy + for me. You wont be dissapointed when you compare this to the stock one, well worth it!
