This aFe Power differential cover brings performance engineering to your axle. Cast from durable aluminum with reinforced ribs and built-in internal/external cooling fins, it increases gear-oil capacity over stock and adds a neodymium magnetic drain plug, a calibration plug set to the factory fill level to prevent overfilling, and an oil-level sight glass for quick inspection. Mounting hardware is included.
