aFe Power Rear Diff Cover Black w/Machined Fins 17-23 Ford F-350/F-450 6.7L (td) Dana M300-14 (Dually)

aFe Power rear differential cover protects and cools the Dana M300 axle on 2017-2023 Ford F-350 and F-450 Super Duty dually trucks with 6.7L diesel engines. Cast from A356-T6 aluminum this cover holds 5 quarts of gear oil compared to the factory 4 quarts for better lubrication during heavy towing. Internal and external fins transfer heat away while magnetic plugs capture metal particles for longer axle life.

Key Features

  • 5 Quart Capacity: Holds 5 quarts at factory fill level versus stock 4 quarts to keep differential fluid circulating in high-heat conditions
  • Cooling Fins: Internal and external machined fins expand surface area for efficient heat dissipation from gear oil
  • Magnetic Plugs: Deep-reach magnetic drain and fill plugs trap ferrous debris to prevent gear damage
  • Oil Sight Glass: Large sight glass with 1/8-inch NPT calibration plug matches factory level to avoid overfilling
  • Cast Aluminum Build: A356-T6 aluminum with reinforcing ribs and black powder coat withstands heavy-duty use

Product Notes

  • Mounting hardware gasket and seals included for direct bolt-on fit
  • Designed for Dana M300-14 bolt pattern axles on dually models
  • 17.8 lbs product weight ships in one box measuring 20 x 15 x 5 inches

Installation Notes

  • Professional installation recommended.
  • Drain old fluid before installing new cover and refill to sight glass level
  • All hardware provided bolts to factory locations on Dana M300 axle
