Key Features

Engineered for durability and ease of maintenance, the PPE Rear Differential Cover includes a range of thoughtful features:

• Constructed from thick, cast nodular iron for maximum strength and impact resistance
• Transverse gussets reinforce the differential housing, reducing flex under high torsion loads
• Recessed hardware design protects mounting bolts from damage during off-road use
• High and low fluid check ports accommodate pinion angle changes common with lifted vehicles
• Convenient top-fill port simplifies oil servicing and fluid changes
• Each service plug contains a high-temperature-rated neodymium magnet to capture ferrous metal particles, preserving fluid quality
• Optimized shape enhances vehicle approach and departure angles for improved off-road capability
• Direct bolt-on replacement for the factory stamped steel cover with no modifications required

Construction & Design

The PPE Rear Differential Cover is expertly cast from nodular iron, a material known for its superior tensile strength and toughness compared to standard cast iron or stamped steel. This robust construction ensures the cover can endure impacts and stresses encountered during off-road driving, protecting internal differential components from damage.

Its design incorporates transverse gussets that add rigidity to the differential housing, minimizing flex and maintaining structural integrity under extreme torque loads. The flange features recessed mounting hardware, which shields bolts from potential damage and contributes to a clean, streamlined appearance. Fluid check ports and a top-fill port demonstrate a practical approach to maintenance, making fluid inspection and servicing easier and more efficient.
