Heavy Duty Cast Aluminum Rear Differential Cover for RAM 1500 9.25"-12

Excessive heat can degrade the protective qualities of differential fluid, leading to accelerated wear of gears and bearings. In limited-slip differentials, constant high temperatures can break down clutch packs and friction modifiers, resulting in reduced efficiency and compromised traction control.

Cast from high-grade A356.0-T6 aluminum alloy, the PPE differential cover adds .5 quart of fluid capacity and features half-inch external cooling fins for long-lasting heat management and performance.

Built-in windage scrapers inside the PPE cover ensure precise fluid distribution around the gears. By reducing excessive fluid churning, these scrapers lower heat buildup and minimize parasitic loss, promoting more efficient power transfer. Together with the vertical external fins, they form a strong cross-bracing structure that improves load distribution and enhances impact resistance.

The fill plug is precisely positioned at the factory level. Both the fill and drain plugs feature a powerful, high-temperature-rated neodymium magnet that captures ferrous particles for added protection.

Fits and looks great!

It fit and looks great on my 2020 RAM 1500 with 3.92 rear gears. I am not sure if the capacity is "slightly" increased over stock, but it seems i was able to put maybe .25-0.5 qts more than what i recall the stock cover holding.

Parts feels beefy and very well made, the fill bolt has an o-ring for sealing, i am not sure how long this will last, or if it will seal properly, but time will tell. I may put a little bit of gasket maker on the threads to seal it better.
