Key Features

Built to deliver superior strength and functionality, the PPE Front Differential Cover incorporates advanced design elements that enhance durability and serviceability:

• Constructed from thick, high-strength nodular iron for maximum impact resistance and longevity
• Transverse gussets reinforce the differential housing, reducing flex and increasing structural rigidity under torsional loads
• Optimized shape improves approach and departure angles, enhancing off-road capability
• Recessed hardware within the flange protects bolts from damage and debris exposure
• High and low fluid check ports accommodate pinion angle changes commonly found on lifted vehicles
• Service plugs equipped with high-temperature-rated neodymium magnets capture ferrous metal particles, helping maintain clean differential fluid
• Direct bolt-on replacement for the factory stamped steel cover—no welding, cutting, or modifications required
• OEM part number reference Mopar 68464903AA for easy verification and compatibility

Construction & Design

The PPE Front Differential Cover is expertly crafted from nodular iron, a material renowned for its exceptional strength and impact resistance. This heavy-duty casting is significantly thicker than the factory stamped steel cover, providing superior protection against rocks, trail debris, and other off-road hazards. The inclusion of transverse gussets enhances the structural integrity of the differential housing, minimizing flex and potential damage during high-torque or extreme off-road conditions.

Designed with lifted vehicles in mind, the cover features strategically positioned fluid check ports that accommodate changes in pinion angle, ensuring accurate fluid level readings and simplifying maintenance. Additionally, the recessed hardware design protects mounting bolts from impacts and debris, extending fastener life and maintaining a secure seal under all conditions.

Installation of the PPE Nodular Iron Front Differential Cover is straightforward and user-friendly. This cover is a direct bolt-on replacement for the factory stamped steel cover on Jeep Wrangler JL (2018–2025) and Jeep Gladiator JT (2020–2025) models equipped with the Dana 44 - M210 front axle. No welding, cutting, or special modifications are necessary, making it accessible for both professional installers and experienced DIY enthusiasts.
