aFe Power Rear Diff Cover Black with Machined Fins for 17 Ford F-350/F-450 6.7L Dana M300-14 Dually

This rear differential cover enhances the protection and performance of the axle's differential. Crafted from durable A356-T6 cast aluminum, it features reinforcing ribs that ensure maximum strength under demanding conditions. The design incorporates a large oil level sight glass along with a calibration plug, which is set to the factory level, effectively preventing any risk of overfilling.

With a 5-quart gear oil capacity, this cover significantly increases oil retention compared to factory options which hold only about 4 quarts. Built-in internal and external cooling fins maximize the surface area, facilitating superior cooling of the differential oil, which is essential for maintaining optimal performance.

The inclusion of a magnetic drain plug and a deep reach magnetic fill plug ensures enhanced protection against metal wear, capturing contaminants to prolong the life of the differential. Finished with a sleek black powder-coat and machined fins, this component combines functionality with an attractive aesthetic.
