aFe POWER Front & Rear
Diff GUARD Packages
for Various Diesel Trucks
Upgrade to the aFe POWER Diff GUARD that does more than just look good — it boosts cooling, strength, and longevity. Its finned aluminum construction dissipates heat far better than stock steel, keeping fluid temps down for smoother performance and longer gear life, whether you’re towing, off-roading, or pushing your rig hard.
Engineered for the Long Haul
- Built-in Internal/External Fins: Built-in internal and external fins transfer heat from the oil to the outside air for maximum cooling.
- Increased Oil Capacity: These covers have an increased oil capacity over stock for better performance over a longer duration.
- Magnetic Plugs: This system incorporates magnetic drain and deep reach fill plugs to capture loose particles for maximum protection.
- Oil Level Sight Glass: Each cover includes an oil level sight glass that allows for quick and easy oil inspection.
- Constructed from Durable Cast Aluminum
- Powder Coat Finish
aFe Power’s Pro Series Front and Rear Differential Covers bring performance-driven protection to your drivetrain. Constructed from durable cast aluminum and designed with reinforced ribs, these covers offer enhanced strength and improved heat dissipation for demanding driving conditions.
This is a complete, ready-to-install kit that includes front and rear differential covers, all necessary hardware, and 6 quarts of 75W-90 premium PROGUARD Synthetic gear oil —everything you need for a full service in one convenient package.
