Dana 44 Wrangler JL Gladiator and Bronco 4.56 Ratio Rear 2-Cut Ring and Pinion Revolution Gear

This Revolution Gear and Axle rear ring and pinion set (D44-M220-456DC-REV) is designed for Dana 44 / M220 rear axle differentials. It is compatible with 2018 and newer Jeep Wrangler JL, 2020 and newer Jeep Gladiator JT models, specifically those with Rubicon trim levels. The gear set features a 4.56 ratio and is manufactured using a 2-cut (Face Hobbed) gear cutting style followed by lapping, which reduces noise and increases load-carrying capacity compared to traditional face-milled gears. Made from high-grade 8620 heat-treated steel, these gears are engineered for enhanced capability and performance, improving torque delivery and towing performance. The optimized gear ratio can also contribute to better fuel efficiency at highway speeds. Revolution Gear and Axle emphasizes easy installation and quiet operation, backed by a 2-year warranty against manufacturing defects.
