What is this part?
It's the aFe Power Pro Series rear differential cover, MPN 46-70022 (4670022), made of cast aluminum with a black powder coat finish and machined fins.
Does it hold more oil than the stock cover?
Yes. It offers increased oil capacity over stock, and built-in internal and external fins transfer heat from the oil to the outside air for added cooling.
What do the magnetic plugs do?
Dual neodymium magnetic plugs — a magnetic drain and a deep-reach fill plug — help capture loose metal particles in the oil for added gear protection.
How do I check the oil level?
A pre-installed oil level sight glass lets you inspect the oil quickly, and a calibration plug set to the factory oil level helps prevent overfilling.
Which vehicles does it fit?
It fits the 2000-2005 Ford Excursion, 1986-1996 F-250, 1997 F-250 HD, 1999-2025 F-250 Super Duty, 1986-1997 F-350, and 1999-2025 F-350 Super Duty. See the Buyer's Guide tab.
