10.5" Axle Assembly 3.55 Posi LSD

The Zumbrota Drivetrain RAA435-160A-P is a remanufactured complete axle assembly, meticulously rebuilt to ensure precision and reliability. This assembly is specifically designed for the 10.5-inch Ford axle found in 2008-2010 Ford F250 and F350 models equipped with the 6.4L engine and Single Rear Wheel (SRW) configuration. It comes with a 3.55 gear ratio and a Posi Limited Slip Differential (LSD) for enhanced traction. The remanufacturing process involves a comprehensive inspection of all internal components, including ring and pinions, internal gears, clutches, and carriers, to meet the highest quality standards. All bearings and seals are replaced as a matter of course. The gears are meticulously inspected for optimal tooth contact patterns and set to the correct rolling torque using inch-pound measurements, ensuring precise setup and extended longevity. Furthermore, correct gear backlash is established to guarantee proper gear lubrication and quiet operation, while axle tubes are inspected and straightened to OEM specifications. Zumbrota employs an exclusive cleaning procedure that includes hydro-blast rinsing and sandblasting on both internal and external parts, followed by a proprietary shot-enticed deep cleaning. This rigorous process sets a high standard for axle assembly remanufacturing, ensuring that housings are cleaned to an OEM finish and tested for surface wear and cracks. This axle assembly is built to order and includes a refundable core charge. It is backed by a 2-year limited warranty.
