Industry-Leading Fluid Cooling for your Super Duty

When you put your truck through tough jobs like towing, hauling, or off-roading, your differential takes on a lot of heat and stress. The PPE 10.25/10.5-12 Sterling Heavy-Duty Black Cast Aluminum Rear Differential Cover is designed to keep temperatures down, improve durability, and extend the life of your drivetrain. By upgrading from the thin factory cover to this high-strength cast aluminum replacement, you're giving your truck the cooling power and protection it needs to handle hardcore applications without breaking a sweat. One of the key benefits of this cover is its increased fluid capacity, which helps reduce heat buildup and maintain proper lubrication. More oil volume means better heat dispersion, which is critical for anyone who tows heavy loads, drives long distances, or pushes their truck with performance upgrades. To take cooling even further, this cover features deep external cooling fins and internal heat sinks, maximizing surface area to pull heat away from the differential. This results in lower fluid temperatures, better oil viscosity, and longer-lasting components.

Durable Construction with User-Friendly Design

Durability is a major advantage of this cover. Unlike factory steel covers that can warp or rust over time, this one is built from A356-T6 cast aluminum, a material known for its superior strength, impact resistance, and ability to handle extreme conditions. PPE also reinforces the structure with triangulated gussets, preventing flex in the gear housing and ensuring long-term reliability. Additionally, the black powder-coated finish gives this cover a sleek, modern appearance while adding an extra layer of protection against rust and corrosion. Maintenance is made simple with stainless steel service plugs, including a high-power neodymium magnet-equipped fill plug. This magnet captures metal shavings and debris that circulate through the fluid, preventing them from damaging your gears. Keeping these contaminants out helps extend service life and reduces wear on your differential components.
