4.56 Open Differential Carrier

The Zumbrota Performance Axle is a remanufactured front axle assembly specifically designed for Chrysler 9.25 differentials. With a 4.56 gear ratio and an open differential configuration, this assembly is engineered to meet the demands of enhanced performance, whether for larger tires, increased horsepower, or heavier towing capabilities. Zumbrota ensures the highest quality standards in their remanufacturing process. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are meticulously inspected and tested. To guarantee optimal setup and longevity, all bearings and seals are replaced, and gear sets are inspected for proper tooth contact patterns and correct rolling torque. The remanufacturing process includes Zumbrota's exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peening deep cleaning process, setting a high standard for axle assembly rebuilds. This attention to detail ensures that the axle assembly is ready to handle increased stress and provide reliable performance.
