238053222

Overview:

The PPE Rear Differential Cover is a robust upgrade designed specifically for the Dana 44-M220 rear differential found on Jeep Wrangler models from 2018 to 2025 and Jeep Gladiator models from 2020 to 2025. This heavy-duty cover replaces the factory stamped steel cover with a thick nodular iron construction, providing superior strength and durability for off-road enthusiasts and daily drivers alike. Engineered to enhance your vehicle’s approach and departure angles, it ensures better clearance and protection when tackling rugged terrain.

Ideal for Jeep owners who demand reliability and toughness from their drivetrain components, this differential cover is built to withstand the high torsional stresses encountered during off-road adventures. Its design incorporates transverse gussets that reinforce the housing, preventing flex and potential damage under extreme conditions.

Key Features:

Designed with both durability and serviceability in mind, the PPE Rear Differential Cover offers a range of features that enhance protection and maintenance convenience:

• Constructed from thick, high-strength nodular iron for maximum durability
• Transverse gussets add rigidity and prevent housing flex under heavy loads
• Optimized shape improves approach and departure angles for off-road clearance
• Recessed hardware within the flange protects bolts from damage
• High and low fluid check ports accommodate pinion angle changes from lifted suspensions
• Top-fill port simplifies differential fluid servicing
• Each service plug contains a high-temperature-rated neodymium magnet to capture ferrous metal particles
• Direct bolt-on replacement for factory stamped steel covers—no modifications required

Construction & Design:

The PPE Rear Differential Cover is expertly crafted from nodular iron, a material known for its excellent strength and impact resistance compared to standard cast iron or stamped steel. This heavy-duty construction ensures that the cover can endure the rigors of off-road driving, including impacts from rocks and debris. The thick casting also helps dissipate heat more effectively, contributing to improved differential longevity.

Strategically placed transverse gussets reinforce the cover and the differential housing, reducing flex and maintaining structural integrity under high torsional loads. The cover’s profile is carefully engineered to maintain or improve your Jeep’s approach and departure angles, minimizing the risk of damage when navigating obstacles.

Installation & Fitment:

This rear differential cover is designed as a direct bolt-on replacement for the Dana 44-M220 rear differential found on 2018–2025 Jeep Wrangler and 2020–2025 Jeep Gladiator models. Installation is straightforward and requires no modifications to your vehicle’s drivetrain or suspension. The included hardware is recessed within the flange to protect against off-road impacts, ensuring long-lasting secure attachment.

The inclusion of high and low fluid check ports makes it easier to monitor fluid levels, especially important for lifted vehicles where pinion angles change. The top-fill port simplifies fluid changes, reducing maintenance time and effort.

What’s Included
