Upgrade your Ford SuperDuty truck with this PPE Heavy-Duty Cast-Aluminum Differential Cover. It delivers industry-leading efficiency, optimal gear lubrication, and exceptional fluid cooling, far surpassing the capabilities of the stock stamped steel cover.

Cast from high-grade A356-T6 aluminum, our differential cover provides unparalleled toughness and cooling performance. This ensures performance under the most demanding conditions, offering peace of mind that the stock cover can't match.

PPE Differential Cover is equipped with innovative internal fluid windage scrapers that ensure optimal fluid distribution around the gears. These scrapers baffle excessive fluid, reducing unnecessary fluid resistance and heat buildup, and enhancing the operating efficiency of the rear end.

Featuring deep external cooling fins, the PPE cover significantly increases the heat-dissipating surface area. This design helps maintain the differential fluid within its optimal operating temperature range, extending the service life of your differential by preventing overheating and fluid degradation.

To ensure your differential fluid stays clean and effective, PPE incorporates exclusive magnetic drain and fill plugs to our diff cover. These high-power, heat-resistant neodymium magnets attract and capture harmful ferrous metal particles, reducing wear on your differential components and promoting a longer fluid lifespan.

Whether you're hauling heavy loads or tackling rugged terrain, trust PPE to keep your differential running smoothly and efficiently.

Fitment Note:
