Ford 10.5" Rear Axle Assembly 4.30 Ratio Yukon Duragrip

This rear axle assembly is specifically built for the Ford 10.5" differential, featuring a 4.30 gear ratio and a Yukon Duragrip limited-slip differential for enhanced performance. Each Zumbrota drivetrain axle assembly is remanufactured to exacting standards of precision and reliability. The process includes thorough inspection of the axle tubes for straightness and the housings for surface wear and cracks. All internal components, including ring and pinions, gears, clutches, and carriers, are meticulously inspected and tested. Additionally, all bearings and seals are replaced with new parts, and gears are inspected for optimal tooth contact patterns and correct rolling torque. The remanufacturing process also includes Zumbrota's exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning treatment, setting a high standard for axle assembly remanufacturing. This attention to detail ensures that the assembly is ready to handle demanding performance requirements, whether for larger tires, higher horsepower applications, or heavy towing needs. This specific assembly is designed for 2011-2016 Ford F250 and F350 models equipped with the Ford 10.5" rear axle. It incorporates aftermarket gear upgrades and options for limited-slip differentials or lockers to provide customized performance tailored to the owner's driving style.
