aFe Pro Series Front Differential Cover: w/ Machined Fins and Gear Oil

aFe Pro Series Front Differential Cover

Universal Fitment

46-70402-WL

Overview:

The aFe Pro Series Front Differential Cover is a premium upgrade designed to enhance the durability and cooling efficiency of your vehicle’s front differential. Crafted from rugged cast aluminum with machined cooling fins, this cover increases fluid capacity and improves heat dissipation, helping to extend the life of your differential components. Ideal for enthusiasts and off-roaders who demand reliable performance and easier maintenance, this cover also includes high-quality synthetic gear oil to ensure optimal lubrication right out of the box.

By replacing your stock stamped steel differential cover with this finned aluminum design, you gain superior cooling capabilities that reduce gear oil temperatures during heavy use. This results in improved gear protection and longer service intervals, making it a smart investment for vehicles subjected to towing, off-roading, or high-performance driving conditions.

Key Features:

Engineered for enhanced protection and cooling, the aFe Pro Series Front Differential Cover offers a range of advanced features:

• Constructed from durable die-cast A380 aluminum for strength and longevity
• Wrinkle black powder-coated finish provides corrosion resistance and a sleek appearance
• Machined cooling fins cast into the cover increase surface area for improved heat dissipation
• Includes dual neodymium magnetic drain plugs to capture metal particles and protect gears
• Large oil level sight glass with calibration plug set to factory oil level to prevent overfilling
• Comes pre-filled with 3 quarts of PRO Guard D2 synthetic 75W-90 gear oil for immediate use
• 1/8" NPT port for optional temperature sensor installation to monitor fluid temperature
• Reinforced ribs integrated into the design for added structural integrity

Construction & Design:

The Pro Series Front Differential Cover is precision-crafted from die-cast A380 aluminum, a material known for its excellent strength-to-weight ratio and thermal conductivity. The cooling fins are machined directly into the cover, maximizing heat transfer away from the gear oil to maintain optimal operating temperatures. Reinforced ribs add rigidity to withstand harsh driving conditions and impacts, while the wrinkle black powder-coated finish protects against corrosion and wear, ensuring the cover maintains its rugged appearance over time.

Installation & Fitment:

Designed for straightforward installation, this differential cover replaces the factory stamped steel cover without requiring modifications. The included magnetic drain plugs simplify fluid changes by allowing easy draining without removing the entire cover. The increased fluid capacity and cooling efficiency help maintain lower operating temperatures, which can extend the life of your differential components. While the cover fits a wide range of applications, always verify compatibility with your specific vehicle before purchase.

What's Included:

• Pro Series Front Differential Cover with machined cooling fins
• 3 quarts of PRO Guard D2 synthetic 75W-90 gear oil
• Dual neodymium magnetic drain plugs
• Oil level sight glass with calibration plug
• Installation hardware

Ideal For:

This differential cover is perfect for off-road enthusiasts, performance drivers, and anyone looking to improve the reliability and longevity of their front differential. It is especially beneficial for vehicles used in towing, hauling, or extreme driving conditions where heat buildup can compromise gear oil performance. Upgrade your differential protection and cooling with a product engineered for durability and efficiency.
