Advanced FLOW Engineering Differential Cover (MPN: 46-71260B)

Enhanced oil capacity and cooling for AAM 11.5/12 rear axles.

The Advanced FLOW Engineering Differential Cover is designed for AAM 11.5 and 12 rear axles, providing superior performance through increased oil capacity. Constructed from durable cast aluminum, this cover features a black powder-coated finish with machined fins that enhance heat dissipation. The built-in internal and external fins effectively transfer heat from the oil to the surrounding air, ensuring optimal cooling during operation.

This differential cover is equipped with dual neodymium magnetic plugs that capture loose particles, offering maximum protection for the gears. A large oil level sight glass allows for quick and easy inspection of oil levels, while a calibration plug is set to the factory oil level to prevent overfilling. The inclusion of both a drain plug and a deep reach fill plug further enhances the utility of this cover, making maintenance straightforward and efficient.
