Key Features

This rear differential cover incorporates several advanced features to enhance protection and performance:

• Increased 4-quart lube capacity at the factory fluid level line for improved lubrication and cooling
• Magnetic drain plug and magnetic fill plug to capture and remove metal debris, preventing contamination
• Built-in external cooling fins that dissipate heat efficiently, reducing fluid temperature under heavy loads
• Large oil level sight glass with a calibration plug set to factory fluid level to prevent overfilling
• Durable die-cast A356 aluminum construction with reinforced ribs for maximum strength and rigidity
• Wrinkle black powder-coated finish for corrosion resistance and a rugged appearance
• Direct bolt-on design for easy installation without modifications

Construction & Design

The aFe Pro Series Rear Differential Cover is crafted from premium die-cast A356 aluminum, known for its excellent strength-to-weight ratio and thermal conductivity. Reinforced ribs add structural integrity, ensuring the cover resists impacts and flexing under demanding conditions. The wrinkle black powder-coating not only enhances corrosion resistance but also provides a durable, attractive finish that complements the rugged look of your truck’s undercarriage.

Engineered with integrated cooling fins, the cover efficiently transfers heat from the differential fluid to the surrounding air, helping to maintain optimal operating temperatures and prevent premature wear. The inclusion of magnetic plugs for both draining and filling ensures that metallic debris is captured before it can circulate through the differential, protecting internal gears and bearings.
