Construction & Design

The aFe Pro Series Front Diff Cover is crafted from premium cast aluminum, chosen for its excellent strength-to-weight ratio and resistance to corrosion. The cover’s wrinkle-black powder-coated finish not only provides a tough protective layer but also adds a distinctive, aggressive look that complements the rugged styling of the Jeep Wrangler.

Machined fins are integrated into both the internal and external surfaces of the cover to maximize heat dissipation. This design helps maintain cooler operating temperatures within the differential, reducing the risk of overheating and extending the life of the gear oil and internal components. The precision engineering ensures a secure fit on Dana M186 front axles, maintaining factory-level sealing and durability.
