Built For The Long Haul With Performance That Lasts

If you’re looking to give your Ford Super Duty some real longevity and protection where it counts, the aFe Pro Series Differential Cover & Fluid Kit is a smart upgrade that pays off over time. This isn't just a flashy piece of hardware, it's built from rugged cast aluminum and finished with a black powder coat and machined fins that look as tough as they perform. Whether you’re towing heavy loads or hitting the trails, that increased oil capacity keeps your rear differential running cooler and smoother for longer stretches. The included PRO Guard D2 synthetic gear oil doesn’t just meet GL-5 standards, it exceeds them, giving both open and limited-slip differentials the protection they need. One of the nicest touches for everyday drivers is the built-in sight glass, which makes checking your fluid level as easy as a quick glance. No more mess, no more guesswork. Plus, with magnetic plugs pulling in metal debris and a calibration plug that prevents overfilling, you can count on this kit to keep your axle running clean and efficient mile after mile.

Engineered To Cool Protect And Perform Under Pressure

When it comes to the technical side, the aFe 46-70022-WL Pro Series Differential Cover is thoughtfully designed for serious reliability and thermal management. The internal and external fins aren’t just for show, they actively help transfer heat from the oil to the surrounding air, which is critical when your drivetrain is working hard. By increasing the fluid volume over stock, this cover helps maintain consistent lubrication and cooling, especially under demanding towing or off-road conditions. The magnetic drain and deep-reach fill plugs serve a dual purpose by capturing harmful metal particles and ensuring clean gear operation during fluid changes. You’ll also appreciate the included calibration plug, engineered at a precise level to stop you from overfilling, a common issue that can lead to leaks or pressure problems. Every component, including the o-ring seal and mounting hardware, is included so installation is clean and straightforward. It fits 1986-2021 Ford F-250 and F-350 models with 10.25 or 10.5 rear axles, and it’s important to note it’s not for dually setups. From cooling to convenience, this cover is a solid investment in your truck’s drivetrain health.
