• Durable cast aluminum construction with reinforced ribs for maximum strength and impact resistance
• Machined cooling fins on both internal and external surfaces to efficiently dissipate heat and maintain optimal fluid temperature
• Magnetic drain plug captures metal particles and debris, preventing contamination and wear inside the differential
• 1/8" NPT calibration plug preset to factory fluid level to prevent accidental overfilling during maintenance
• Includes all necessary hardware for straightforward, bolt-on installation
• Raw finish allows for custom painting or powder coating to match your vehicle’s aesthetic
• Specifically designed for Dana M220 12-bolt rear axles on Jeep Wrangler JL (2018–2026) and Gladiator JT Rubicon (2020–2025)

Construction & Design

This rear differential cover is crafted from high-quality cast aluminum, chosen for its excellent strength-to-weight ratio and corrosion resistance. The cover’s reinforced ribbing enhances structural integrity, protecting the differential housing from impacts and stresses encountered during off-road driving.

Engineered with precision-machined fins on both the inside and outside surfaces, the design maximizes heat transfer from the differential fluid to the surrounding air. This cooling effect helps maintain proper fluid viscosity and reduces the risk of overheating, which can degrade differential components over time.

The raw finish provides a versatile base for customization, allowing owners to tailor the appearance to their preferences while maintaining the cover’s rugged functionality.

Installation & Fitment

The aFe Power Street Series Rear Differential Cover is designed for a direct bolt-on installation with no modifications required. It fits the Dana M220 12-bolt rear axles found in 2018–2026 Jeep Wrangler JL and 2020–2025 Gladiator JT Rubicon models. Installation is straightforward and can be completed with basic hand tools, making it accessible for both professional mechanics and experienced DIY enthusiasts.

All necessary mounting hardware is included, and the included magnetic drain plug and calibration plug simplify fluid maintenance and help ensure proper fill levels.
