3.55 Posi Traction Complete Axle Assembly

The Zumbrota Drivetrain RAA435-2051A-P is a remanufactured complete axle assembly engineered for specific Ford 9.75" rear-end applications. This unit comes equipped with a 3.55 gear ratio and a Posi Traction limited-slip differential, designed to provide enhanced traction and performance. Zumbrota Drivetrain adheres to stringent rebuilding processes, ensuring each complete axle assembly meets high standards for precision and reliability. Internal components, including the ring and pinion, internal gears, clutches, and carriers, undergo a 100% inspection. The housings are meticulously cleaned through a state-of-the-art hydro-blasting and rinsing procedure, followed by sandblasting and a proprietary shot-enticed deep cleaning process to restore them to OEM finish. Housings are also tested for surface wear and cracks. Precision is a key focus in the remanufacturing process. Correct rolling torque is established using inch-pound measurements for precise setup and longevity, and gear backlash is carefully set to ensure proper gear lubrication and quiet operation. All axle tubes are inspected to confirm they are straightened to OEM specifications. This comprehensive approach ensures a reliable and durable product. It is important to note that this product is an assembly only; axles are not included. Due to the specialized nature of drivetrain components, Zumbrota Drivetrain and JEGS Performance Products emphasize the importance of providing accurate vehicle information, including year, make, model, and VIN, via their SureFit Order Form to ensure the correct product is supplied for your application.
