Key Features

Engineered for strength, performance, and ease of maintenance, the aFe Machined Fins Differential Cover includes the following key features:

• 2-quart lube capacity at the factory fluid level line for optimal oil volume
• Magnetic drain plug to capture and remove metal debris from the differential fluid
• Magnetic fill plug to further prevent contamination inside the differential
• Large oil level sight glass with a calibration plug set to factory fluid level to prevent overfilling
• Durable nodular (ductile) iron construction for superior strength and impact resistance
• Wrinkle black powder-coated finish for corrosion resistance and a rugged appearance
• Precision-machined fins to improve heat dissipation and maintain cooler operating temperatures
• Includes premium 75W-90 gear oil formulated for high-performance differentials

Construction & Design

The differential cover is crafted from nodular iron, also known as ductile iron, which offers exceptional toughness and resistance to cracking under stress. This material choice ensures the cover can withstand off-road impacts and harsh driving conditions without compromising structural integrity. The wrinkle black powder-coated finish not only enhances corrosion resistance but also provides a durable, attractive surface that complements the rugged aesthetic of Jeep vehicles.

Machined cooling fins are integrated into the design to increase surface area, promoting efficient heat dissipation. This helps maintain optimal differential temperatures, reducing the risk of overheating and extending the life of internal components. The inclusion of magnetic plugs and a calibrated sight glass demonstrates a focus on practical maintenance and fluid management, making it easier to monitor and service your differential.

Installation & Fitment

The aFe Machined Fins Differential Cover is designed as a direct bolt-on replacement for the front differentials of select Jeep Grand Cherokee and Wrangler models from 1997 through 2018. Installation requires no modifications, making it a straightforward upgrade for experienced DIYers or professional mechanics. The included magnetic plugs and sight glass simplify fluid changes and inspections, reducing downtime and maintenance effort.
