Description
aFe POWER Street Series Raw Rear Differential Cover with Machined Fins
Upgrade rear-end protection and thermal management with the aFe POWER Street Series Rear Differential Cover, engineered for strength, cooling efficiency, and long-term reliability. Designed specifically for AAM 11.5 and 12.0 rear axles, this differential cover is constructed from durable cast aluminum and finished in a raw appearance with precision-machined cooling fins.
Featuring increased oil capacity, integrated cooling fins, and a magnetic drain plug, this cover improves lubrication performance while reducing operating temperatures—ideal for towing, hauling, and high-load applications.
Key Features & Benefits
Increased Oil Capacity
This differential cover offers greater oil capacity than the factory cover, helping maintain consistent lubrication and improved performance during extended driving, towing, or high-heat conditions.
Integrated Internal & External Cooling Fins
Built-in internal and external fins maximize heat dissipation by transferring heat from the differential oil to surrounding air, reducing operating temperatures and extending component life.
Heavy-Duty Cast Aluminum Construction
Manufactured from high-strength cast aluminum, this cover delivers superior durability and rigidity while maintaining excellent thermal conductivity.
Neodymium Magnetic Drain Plug
A high-strength neodymium magnetic drain plug captures fine metal particles circulating in the gear oil, providing enhanced protection for gears and bearings.
Factory-Level Calibration Plug
The integrated calibration plug is set to the factory oil level, ensuring accurate fluid filling and preventing overfilling, which can lead to foaming or seal damage.
Optional Accessories Available
Compatible with aFe POWER’s deep reach magnetic fill plug (PN: 46-00002) for added protection and service convenience.
