Yukon Duragrip Posi Limited-Slip Differential

The Zumbrota Performance Axle is a remanufactured rear axle assembly engineered for 2004-2008 Ford F-150 models (excluding Heritage). This assembly is equipped with a 4.56 gear ratio and a Yukon Duragrip Posi limited-slip differential, providing enhanced traction for demanding applications such as towing, off-roading, or high-performance driving. Zumbrota rebuilds each axle assembly to the highest quality standards, ensuring precision and reliability. The process includes thorough inspection of all components, including ring and pinions, internal gears, clutches, and carriers, for straightness, cracks, and surface wear. All bearings and seals are replaced, and gears are inspected for optimal tooth contact patterns and correct rolling torque. Zumbrota employs an exclusive hydro-blast rinse, sandblasting, and proprietary shot-peening process for superior internal and external cleaning, setting a high standard for axle assembly remanufacturing. This specific assembly is for the Ford 8.8 rear end and comes with a 4.56 ratio and the Duragrip Posi differential. It is explicitly designed for the 2004-2008 Ford F-150, excluding Heritage models. Buyers should confirm fitment with their specific vehicle configuration.
