Product Details

aFe Power’s Pro Series front and rear differential covers bring performance-driven protection to your drivetrain. Constructed from durable cast aluminum and designed with reinforced ribs, these covers offer enhanced strength and improved heat dissipation for demanding driving conditions. This is a complete, ready-to-install kit that includes front and rear differential covers, all necessary hardware, and 6 quarts of 75W-90 premium PROGUARD Synthetic gear oil —everything you need for a full service in one convenient package. The supplied gear oil exceeds the performance requirements of API GL-5 recommended for both open and limited slip applications. These covers have an increased oil capacity over stock for better performance over a longer duration. Built-in internal and external fins transfer heat from the oil to the outside air for maximum cooling. This system incorporates magnetic drain and deep reach fill plugs to capture loose particles for maximum protection. Each cover uses a calibration plug set to the factory oil level to eliminate overfilling. Each cover includes an oil level sight glass that allows for quick and easy oil inspection.
