Pro Series Rear Differential Cover Black w/ Machined Fins By AFE Power

You wouldn’t run your engine without a little extra muscle, so why let your axle fall behind? The PRO Series Differential Cover for Dana M250 Rear Axles is here to help keep your rear end cool, lubricated, and running stronger for longer. This bad boy features an increased oil capacity compared to your stock cover, meaning you’ll get improved performance, whether you’re hauling heavy loads or conquering rugged terrain. After all, a well-oiled machine is a happy machine!

But don’t just take our word for it—this cover is packed with features designed to maximize durability and ease of use. With internal and external fins, it helps transfer heat from the oil to the outside air. Translation? Better cooling to keep things from getting too hot under the collar. Whether you’re crawling up a mountain pass or just driving down the highway, your axle will stay cooler, longer.

When it comes to maintenance, this cover makes life a whole lot easier. The magnetic drain plug and deep-reach fill plug work together to capture any stray particles that might be lurking in your oil. This means less wear and tear and more protection for your axle. Plus, the calibration plug ensures you won’t overfill your axle—no guesswork here, just straight-up accuracy.

For quick oil checks, the oil level sight glass lets you eyeball your oil level without having to get your hands dirty (unless you’re the type who likes to work on their ride like a true grease monkey). And installation? A breeze. The cover comes with all necessary mounting hardware and can reuse your factory gasket. No fancy tools required—just a little elbow grease!

Fitment Note: This cover fits Dana M250 Rear Axles, so if that’s what you’ve got, you’re good to go.
