The aFe Pro Series 10 Bolt Dana 80 Differential Cover (46-70032) is purpose-built for heavy-duty truck applications running the massive Dana 80 axle under Ford F-450/F-550 Super Duty trucks and RAM 4500/5500 chassis cabs. It's engineered to handle the extreme torque loads of diesel-powered workhorses and high-horsepower tow vehicles that push their drivetrain to the limit daily.

Crafted from cast A356 aluminum with reinforced ribbing, this cover increases oil capacity by roughly 1.5 quarts over the stamped steel OEM cover. It integrates both internal and external heat-dissipating fins to drop operating temperatures by up to 30°F, while dual neodymium magnetic plugs—one drain, one deep-reach fill—trap ferrous debris before it circulates through your gears. The large sight glass makes fluid checks a 5-second job, and the calibration plug ensures you fill to the exact factory spec every time.

This isn't just a pretty face for your pumpkin. The extra thermal capacity is a game-changer when you're pulling a 15,000-lb trailer up a 6% grade, keeping gear oil from breaking down under sustained heat. Combined with PRO Guard D2 synthetic 75W-90 option, you're looking at extended service intervals and genuine long-haul durability for your high-output powertrain.

Stop cooking your gear oil and start protecting your Dana 80 with aFe's Pro Series engineering. Order yours today and give your diff the cooling capacity it deserves.

Frequently Asked Questions

How does the aFe Pro Series Dana 80 differential cover improve oil capacity over the factory cover?

The aFe Pro Series 10 Bolt Dana 80 differential cover increases oil capacity by approximately 1 to 2 quarts over the stock Dana 80 cover, which helps keep the differential fluid cooler under heavy loads. It is constructed from durable cast aluminum with reinforced ribs for maximum strength, and the machined fins and textured powdercoating give it a distinctive high-performance look. This differential cover also comes in versions with or without PRO Guard D2 synthetic 75W-90 oil, and complete sets are available for both front and rear axles.

What material is the aFe Pro Series Dana 80 differential cover made from?

This aFe Pro Series differential cover is made from high-strength cast aluminum with reinforced structural ribs to resist flex under hard launches and towing. The machined external fins and internal baffling increase surface area for heat dissipation, keeping the Dana 80 differential fluid temperatures lower during sustained highway driving or off-road use. The textured black powdercoat finish protects against corrosion while the machined fin accents provide a custom look that stands out.

Will the aFe Pro Series Dana 80 differential cover fit both front and rear axles on my truck?

Yes, the aFe Pro Series Dana 80 differential cover is available as an individual unit for either the front or rear differential, and aFe also sells complete sets that include both front and rear covers plus PRO Guard D2 synthetic 75W-90 oil. It is a 10-bolt pattern designed specifically for Dana 80 axles found in heavy-duty Ford F-Super Duty trucks and some medium-duty applications. Always verify your axle's bolt pattern and gasket surface before ordering to ensure proper fitment.

Does the aFe Pro Series Dana 80 cover come pre-filled with synthetic gear oil?

Certain versions of this aFe Pro Series differential cover ship pre-filled with aFe's PRO Guard D2 synthetic 75W-90 gear oil, which provides excellent thermal stability and wear protection for high-torque applications. The pre-filled option simplifies installation since you just bolt it on without measuring and pouring fluid separately. If you prefer to use your own gear oil, aFe also sells the cover without oil so you can choose your preferred weight and brand.

How much stronger is the aFe Pro Series differential cover compared to the stamped steel factory cover?

The aFe Pro Series Dana 80 differential cover is significantly stronger than the thin stamped steel factory cover thanks to its cast aluminum construction with thick reinforced ribs that resist flexing under load. While factory covers can distort under hard acceleration or heavy towing, this aftermarket differential cover maintains its shape and keeps the ring and pinion gears properly aligned. The increased rigidity also helps prevent leaks around the gasket surface, which is a common issue with stock covers on high-mileage Dana 80 axles.

What vehicles use a Dana 80 axle that would fit this aFe Pro Series differential cover?

The Dana 80 axle is commonly found in Ford F-450 and F-550 Super Duty trucks, as well as some medium-duty commercial chassis and motorhome platforms from the late 1990s through current models. This aFe Pro Series 10 Bolt differential cover is engineered specifically for the Dana 80's bolt pattern and housing shape, so it will not fit Dana 60, Dana 70, or Dana S70 axles. If you are unsure of your axle model, check the differential cover's bolt count and the casting numbers on the axle housing before purchasing.
