Dana 60 Rear Axle Assembly 3.55 Posi LSD

The Zumbrota Drivetrain RAA435-2137A is a remanufactured complete axle assembly designed for the Dana 60 rear axle. This assembly is built to the highest quality standards, ensuring precision and reliability. It features a 3.55 gear ratio and a Posi Limited Slip Differential (LSD). Each axle assembly undergoes a thorough inspection process. This includes checking for straightness, cracks, and surface wear. All internal components, such as ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. To guarantee optimal performance and longevity, all bearings and seals are replaced. The gears are inspected for proper tooth contact patterns and correct rolling torque, with precise setup ensured through inch-pound measurements. Proper gear backlash is also set to maintain correct lubrication and quiet operation. Zumbrota Drivetrain employs an exclusive cleaning procedure that includes hydro-blast rinsing and sandblasting for both internal and external parts, followed by a proprietary shot-peening deep cleaning process. This meticulous approach sets the standard for axle assembly remanufacturing, ensuring components are restored to OEM specifications. The axle tubes are inspected and straightened to meet OEM standards, and housings are tested for wear and cracks. This specific assembly is designed for 2001-2002 Dodge Ram 2500 models with the Dana 60 rear axle and a 3.55 ratio.
