Key Features

Designed with advanced engineering and practical features, the aFe Pro Series Front Differential Cover delivers enhanced protection and performance:

• Constructed from durable cast aluminum for long-lasting strength and impact resistance
• Wrinkle-black powder-coated finish with precision-machined cooling fins for superior heat dissipation
• Built-in internal and external fins transfer heat efficiently from the gear oil to ambient air, reducing operating temperatures
• Dual neodymium magnetic plugs capture metal particles and debris, protecting gears from premature wear
• Large oil level sight glass allows quick and accurate inspection of fluid level without removal
• Calibration plug preset to factory oil level to prevent overfilling and ensure proper lubrication
• Increased oil capacity compared to stock covers, providing better cooling and longer-lasting gear oil performance
• Includes 2 quarts of PRO Guard D2 synthetic 75W-90 gear oil, exceeding API GL-5 requirements for open and limited-slip differentials
• Specifically designed to fit Jeep Dana M210 front axles for a precise, bolt-on installation

Construction & Design

The aFe Pro Series Front Differential Cover is crafted from high-quality cast aluminum, chosen for its excellent strength-to-weight ratio and superior thermal conductivity. The wrinkle-black powder-coated finish not only enhances corrosion resistance but also provides a rugged aesthetic that complements Jeep’s off-road heritage. Machined cooling fins are integrated both inside and outside the cover to maximize heat transfer, helping to maintain optimal operating temperatures during heavy-duty use.

Magnetic drain and fill plugs utilize powerful neodymium magnets to attract and hold metal shavings and contaminants, preventing damage to internal gears and bearings. The large sight glass is engineered for durability and ease of use, allowing for quick visual checks of gear oil levels without the need to remove the cover or plugs.

Installation & Fitment

This differential cover is designed for a direct bolt-on installation on 2018–2021 Jeep Gladiator and Wrangler models equipped with the Dana M210 front axle and either the 3.0L EcoDiesel or 3.6L V6 engines. Installation requires no modifications and includes all necessary hardware for a secure fit. The included calibration plug ensures the gear oil is filled to the factory-recommended level, simplifying maintenance and reducing the risk of overfilling.
