Dana 70 3.55 Posi Limited Slip Differential Axle

The Zumbrota Drivetrain RAA435-2009A-P is a remanufactured Dana 70 axle assembly, meticulously rebuilt to the highest standards of precision and reliability. This unit boasts a 3.55 gear ratio and a Posi Limited Slip Differential for enhanced traction. It is specifically designed for 2000-2001 Dodge Ram 2500 4x4 models equipped with drum brakes. Each Zumbrota axle assembly undergoes a rigorous inspection process. This includes thorough checks for straightness, cracks, and surface wear on all components. Internals such as ring and pinions, clutches, and carriers are fully inspected and tested. All bearings and seals are replaced, and gears are examined for optimal tooth contact patterns and correct rolling torque, measured precisely in inch-pounds for setup and longevity. Proper gear backlash is set to ensure adequate lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts. This is followed by a proprietary shot-enticed deep cleaning process, establishing a benchmark for remanufactured axle assemblies. The assembly features a 9.75-inch ring gear and a 10-bolt cover. While the cover is included, fluid is not.
