The aFe Street Series Differential Cover 46-71180A is a direct-fit upgrade for Dana 44 axles found in Jeep Wrangler TJ/LJ/XJ, Ford Bronco, and early GM K5 Blazer applications. If you're building a capable off-roader or restoring a classic 4x4, this cover adds genuine cooling and strength benefits over the thin factory stamping.

Cast from high-quality A356 aluminum with a chip-resistant black powdercoat and bright machined fin accents, the 46-71180A increases fluid capacity by approximately 0.75 quarts. The efficient fin geometry reduces fluid temperature by up to 20°F in technical trail driving, while the included magnetic drain plug captures ring-and-pinion wear particles before they damage bearings. The machined sealing surface ensures compatibility with RTV or gasket sealants.

The Street Series is rated for vehicles up to 400 HP and offers significant improvement in impact resistance over stamped steel—important when you're sliding over rocks. The added oil capacity helps lubricate the pinion bearing at extreme approach angles where starvation is a real risk. A budget-conscious upgrade that punches well above its weight class.

Stop running that stamped cover from the factory. Give your Dana 44 the cooling and protection it deserves with aFe Street Series.

Frequently Asked Questions

What vehicles are compatible with the aFe Street Series differential cover for my axle?

The aFe Street Series differential cover is available for a wide range of axles including Dana 35, Dana 44, Dana 60, GM 10-bolt, GM 14-bolt, Ford 8.8-inch, and Ford 9-inch applications. It is constructed from cast aluminum with reinforced ribs for added strength over the stock stamped steel cover. The street series focuses on improved oil capacity and heat dissipation through machined cooling fins, making it ideal for daily drivers and weekend performance builds.

How much does the aFe Street Series differential cover increase fluid capacity?

The aFe Street Series differential cover increases gear oil capacity by roughly 1 to 1.5 quarts depending on the specific axle application, giving you more thermal mass to handle heat buildup during spirited driving. The cast aluminum construction with internal and external fins provides better heat transfer than the factory cover, reducing overall fluid temperatures. This extra capacity also helps keep the ring and pinion gears bathed in oil during hard cornering or off-camber terrain.

Does the aFe Street Series differential cover come with a drain plug and fill plug?

Yes, the aFe Street Series differential cover includes both a magnetic drain plug and a threaded fill plug for easy fluid changes without removing the cover completely. The magnetic drain plug captures metal particles from normal gear wear, keeping them from circulating through the differential bearings. This design makes routine maintenance faster and helps you monitor the health of your ring and pinion by inspecting the magnetic plug for excessive debris at each oil change.

Will the aFe Street Series cover fit my lifted or modified off-road truck?

The aFe Street Series differential cover is designed as a direct bolt-on replacement that maintains the same overall profile as the factory cover, so it will not interfere with suspension components, track bars, or differential skid plates on lifted trucks. However, because it is cast aluminum rather than stamped steel, the cover is more rigid and less likely to dent from rock impacts than a stock cover. If you do extreme rock crawling, you may want to pair this cover with a differential skid plate for additional protection.

What color and finish options does the aFe Street Series differential cover come in?

The aFe Street Series differential cover features a durable black powdercoat finish with machined fin accents that expose the raw cast aluminum for a two-tone custom look. The powdercoat resists scratches, brake dust, and road grime better than painted finishes, keeping your cover looking clean for years. Some applications may also be available in a silver or natural aluminum finish if you prefer a brighter appearance under your vehicle.

How does the aFe Street Series compare to the Pro Series differential cover?

The aFe Street Series differential cover uses cast aluminum with reinforced ribs and machined cooling fins for improved heat dissipation and oil capacity, while the Pro Series steps up with more aggressive finning, additional structural ribbing, and optional PRO Guard D2 synthetic oil. The Street Series is an excellent upgrade for daily drivers and mild performance builds needing better cooling and strength over stock. The Pro Series is better suited for high-horsepower, towing, or off-road applications where maximum heat rejection and durability are critical.
