• Reinforced ribs and machined black powder-coated fins provide maximum structural integrity and stylish appearance
• Built-in internal and external cooling fins efficiently dissipate heat from differential fluid to maintain optimal operating temperatures
• Magnetic drain plug paired with a 6-inch deep reach magnet captures metal particles and debris, protecting internal gears
• Includes a 1/8" NPT calibration plug preset to factory fluid level to prevent overfilling
• Clear sight glass allows for quick and easy fluid level inspection without removal
• Approximately 2-quart fluid capacity at factory fill line, ensuring proper lubrication volume
• All necessary hardware included for straightforward installation

Construction & Design

The differential cover is precision cast from high-quality aluminum, chosen for its excellent strength-to-weight ratio and resistance to corrosion. The black powder-coated finish not only enhances durability but also adds a refined, aggressive look that complements the rugged style of Jeep Wranglers. Reinforced ribs increase the cover’s rigidity, protecting the differential housing from impacts and deformation during off-road use.

Machined fins on both the exterior and interior surfaces maximize heat transfer by increasing surface area, which helps keep the differential fluid cooler during heavy use. This thermal management is critical to maintaining the longevity and performance of the axle components.

Installation & Fitment

Installation of the aFe Street Series Dana 30 Diff Cover is designed to be simple and hassle-free. The cover fits directly onto the front Dana 30 axle housings of Jeep Wranglers from 1997 to 2018, including models with 2.5L I4, 4.0L I6, 3.8L V6, and 3.6L V6 engines. No modifications or special tools are required, and the package includes all necessary mounting hardware.

The included calibration plug and sight glass simplify fluid maintenance by ensuring the correct fill level and allowing quick visual checks, reducing the risk of overfilling or leaks.
