Key Features

The aFe Pro Series Rear Diff Cover incorporates several advanced features designed to maximize gear protection and cooling efficiency:

• Constructed from durable cast aluminum for long-lasting strength and corrosion resistance
• Red powder coat finish with machined fins for enhanced heat dissipation and visual appeal
• Increased oil capacity compared to stock covers, allowing for better lubrication and extended performance
• Built-in internal and external fins that transfer heat from the oil to the outside air, improving cooling efficiency
• Dual neodymium magnetic plugs (drain and fill) that capture metal particles to protect gears from wear
• Large oil level sight glass for quick and easy inspection of fluid levels without removal
• Calibration plug preset to factory oil level to prevent overfilling and ensure optimal fluid volume
• Includes sway bar spacers to maintain proper suspension geometry after installation

Construction & Design

Crafted from high-quality cast aluminum, the aFe Pro Series Rear Diff Cover offers superior strength and resistance to the harsh environments encountered during off-road driving. The red powder coat finish not only protects against corrosion but also provides a distinctive look that complements the rugged styling of the Jeep Gladiator.

Precision-machined fins on both the internal and external surfaces increase the surface area for heat transfer, effectively dissipating heat generated by the differential gears. This design helps maintain optimal operating temperatures, reducing the risk of overheating and extending the life of your differential components.

Installation & Fitment

This rear differential cover is a direct fit replacement for the Dana M220 rear axle on 2020 to 2023 Jeep Gladiators. Installation requires no modifications and can be completed with basic hand tools. The included calibration plug ensures the oil level is set precisely to factory specifications, simplifying the fill process and preventing overfilling.

Additionally, the included sway bar spacers help maintain proper suspension alignment after installation, ensuring your vehicle’s handling remains consistent.
