Material and Performance Excellence
The differential case is manufactured from a high-strength, nodular cast iron, a material chosen for its exceptional toughness and superior fatigue resistance compared to standard gray iron. This robust construction is crucial for withstanding the high shock loads and constant stress encountered during off-road use and daily driving. The material's excellent damping characteristics also contribute to quieter gear operation. The internal gears are precision-milled from case-hardened alloy steel, providing a hard, wear-resistant surface with a tough core to handle the torque demands of the JL's powertrain, ensuring long-term reliability and consistent power transfer to the front wheels.

Precision-OEM Production Process
Manufactured to the strictest quality controls, the Mopar 68398730AA is produced using advanced casting and machining processes. The housing is created through precision sand casting, ensuring optimal grain structure and material integrity. Critical surfaces, including the ring gear flange, bearing journals, and cross pin bore, are finished on CNC machining centers to exacting tolerances. This guarantees perfect ring gear alignment, correct bearing preload, and seamless integration with the existing Dana 44 axle components, preventing premature wear and ensuring optimal performance.
