PPE Nodular Iron Rear Differential Cover

2018–2025 Jeep Wrangler / 2020–2025 Jeep Gladiator Dana 44-M220

Part #: 238053220

Overview

The PPE Nodular Iron Rear Differential Cover is a heavy-duty upgrade engineered specifically for the Dana 44-M220 rear differential found on Jeep Wrangler models from 2018 through 2025 and Jeep Gladiator models from 2020 through 2025. Designed to replace the factory stamped steel cover, this robust nodular iron cover delivers superior strength and durability, making it an essential component for off-road enthusiasts and daily drivers who demand enhanced protection for their drivetrain.

Built to withstand the high torsional stresses and impacts encountered during rugged off-road use, this cover improves your vehicle’s approach and departure angles, providing better clearance and reducing the risk of damage when navigating challenging terrain. Its reinforced design ensures long-lasting reliability and peace of mind on every trail.

Key Features

Engineered for durability and ease of maintenance, the PPE Rear Differential Cover offers a comprehensive set of features that enhance protection and serviceability:

• Constructed from thick, high-strength nodular iron for maximum impact resistance and longevity
• Transverse gussets reinforce the housing to prevent flex and maintain structural integrity under heavy loads
• Optimized shape improves approach and departure angles for enhanced off-road clearance
• Recessed hardware within the flange protects mounting bolts from damage during off-road use
• High and low fluid check ports accommodate pinion angle changes common with lifted suspensions
• Top-fill port simplifies differential fluid servicing, reducing maintenance time
• Each service plug contains a high-temperature-rated neodymium magnet to capture ferrous metal particles and protect internal components
• Direct bolt-on replacement for factory stamped steel covers with no modifications required

Construction & Design

The cover is expertly crafted from nodular iron, a material known for its superior strength and impact resistance compared to standard cast iron or stamped steel. This thick, heavy-duty casting not only protects the differential from rocks and debris but also aids in heat dissipation, contributing to improved differential longevity and performance.

Strategically placed transverse gussets add rigidity to both the cover and the differential housing, minimizing flex and potential damage under extreme torsional loads. The cover’s carefully engineered profile maintains or improves your Jeep’s approach and departure angles, helping to prevent damage when traversing obstacles.

Installation & Fitment

This rear differential cover is designed as a direct bolt-on replacement for the Dana 44-M220 rear differential on 2018–2025 Jeep Wrangler and 2020–2025 Jeep Gladiator models. Installation is straightforward and requires no modifications to the drivetrain or suspension components. The included recessed hardware protects mounting bolts from off-road impacts, ensuring a secure and durable fit.

The inclusion of high and low fluid check ports makes fluid level monitoring easier, especially for lifted vehicles where pinion angles change. The top-fill port further simplifies fluid changes, making routine maintenance faster and more convenient.

What's Included
