afe Rear Differential Cover (Raw; Street Series); Ford Diesel Trucks 86-13 V8 (td) - 46-70020

This cover has 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 cover incorporates a magnetic drain plug to capture loose particles for maximum protection. A calibration plug is set to the factory oil level to prevent overfilling.
