Key Features

The aFe Street Series Front Differential Cover incorporates advanced features to maximize protection and performance:

• Durable cast aluminum construction for strength and corrosion resistance
• Increased oil capacity compared to the stock cover, improving lubrication and cooling over extended use
• Built-in internal and external machined fins that efficiently transfer heat from the differential oil to the surrounding air
• Neodymium magnetic drain plug designed to capture metal particles and debris, preventing gear damage
• Calibration plug preset to the factory oil level to prevent overfilling and ensure optimal fluid volume
• Raw finish with machined fins for a rugged, functional aesthetic
• Optional accessories available, including an oil level sight glass (Part Number: 46-00001) and a deep reach magnetic fill plug (Part Number: 46-00003)

Construction & Design

This front differential cover is crafted from high-grade cast aluminum, chosen for its excellent strength-to-weight ratio and resistance to corrosion. The raw finish with precision-machined fins not only adds a distinctive look but also plays a critical role in heat dissipation. The internal and external fin design increases the surface area exposed to airflow, helping to maintain lower operating temperatures for the differential oil, which is essential for preventing premature wear and maintaining optimal performance.

The inclusion of a neodymium magnetic drain plug is a thoughtful engineering touch, capturing metal shavings and contaminants that could otherwise circulate within the differential, safeguarding internal components. The calibration plug ensures the oil level matches factory specifications, eliminating guesswork during installation and maintenance.

Installation & Fitment

The aFe Street Series Front Differential Cover is a direct bolt-on replacement for Jeep Wrangler models from 2018 through 2025 equipped with the 3.6L V6 and Dana M186 front axles. Installation requires no modifications, making it a straightforward upgrade for enthusiasts and mechanics alike. The cover is designed to fit precisely, maintaining factory sealing surfaces and ensuring leak-free operation when installed with the appropriate gasket or sealant.
