The Zumbrota Performance Axle is a remanufactured rear axle assembly specifically engineered for the Ford 8.8 differential in 2009-2014 Ford F-150 models, featuring a 4.56 gear ratio and a Yukon Duragrip limited-slip differential. It addresses the needs for improved traction, higher speeds, and increased towing capacity, especially when larger tires or more powerful engines are involved. Zumbrota Performance Axles are recognized as a standard in remanufacturing, with each unit undergoing rigorous inspection and testing. This includes verifying the straightness of tubes to OEM specifications, checking housings for cracks and surface wear, and thoroughly inspecting all internal components such as ring and pinions, gears, clutches, and carriers. All bearings and seals are replaced with new parts. The gear setup is meticulously checked for optimal tooth contact patterns and correct rolling torque to ensure precision and longevity. This axle assembly incorporates a Yukon Duragrip limited-slip differential, which provides customized performance and improved traction. The remanufacturing process includes an exclusive hydro-blast rinse, sandblasting, and a proprietary shot-enticed deep cleaning procedure, setting a high standard for quality and reliability in axle assembly remanufacturing.
