Upgrade the front end of your Jeep Wrangler JL with the aFe Pro Series Front Differential Cover (46-71010B), engineered specifically for the Dana M186 front axle. Designed for enthusiasts who push their Jeeps on and off the road, this cover delivers a smart combination of strength, cooling efficiency, and style.

This aFe differential cover is constructed from durable cast aluminum with reinforced ribs to help protect your ring and pinion from trail impacts and heavy use. The robust design adds rigidity to the housing area compared to a thin stamped steel factory cover, making it an excellent upgrade for lifted, larger-tire, or regularly off‑roaded vehicles.

To manage heat and help extend the life of your gear oil, the cover features machined external fins that increase surface area for improved cooling and more consistent differential temperatures in demanding conditions. Many aFe covers also increase fluid capacity versus stock, which further contributes to better thermal control and lubrication stability under load.

The Pro Series front differential cover is finished in a clean black coating with machined fins that complement factory and aftermarket components for a subtle yet performance‑oriented appearance. It is designed as a bolt-on replacement for the Dana M186 front axle cover and includes the necessary hardware for a straightforward installation on compatible Jeep Wrangler JL models. For the best results and proper sealing, professional installation and careful torque and fluid procedures are recommended.

Whether you are tackling rocky trails, towing, or simply want better protection and cooling for your front differential, the aFe Pro Series Front Differential Cover 46-71010B is a functional and cosmetic upgrade over the factory cover. It helps safeguard your gears, supports more stable operating temperatures, and gives your Jeep Wrangler JL’s front axle a purposeful performance look.

Application-specific design for the Dana M186 front axle on Jeep Wrangler JL models
