Protect your heavy-duty drivetrain with the aFe Power Pro Series rear differential cover. Engineered for high-performance protection, this cover is constructed from durable cast aluminum with reinforced ribs for maximum structural integrity. The increased oil capacity over stock ensures better lubrication and temperature stability over long durations, while integrated internal and external fins maximize heat transfer to the ambient air.

This Pro Series system simplifies maintenance with a pre-installed oil level sight glass for quick inspections and a calibration plug set to the factory oil level to prevent overfilling. For maximum gear protection, it features dual neodymium magnetic plugs—including a deep-reach fill plug—to capture loose metallic particles before they cause wear. The wrinkle-black powder-coated finish with machined fins provides a rugged, custom look that stands up to the elements.
