Dana 70 Axle Assembly 3.55 Ratio

The Zumbrota Drivetrain RAA435-1553B is a remanufactured axle assembly built to exacting quality standards for precision and reliability. This unit is specifically designed for the Dana 70 axle and is intended for 1989-1993 Dodge D350 pickup trucks. This axle assembly features a 10.5-inch ring gear and a 3.55 gear ratio, ideal for applications requiring robust performance. It is configured for Dual Rear Wheels (DRW) and is compatible with both 4x2 and 4x4 drivetrains. The assembly includes a 10-bolt cover, is a full-floating axle type, and is specified as being without Posi Traction. Zumbrota Drivetrain ensures each remanufactured unit undergoes thorough inspection for straightness, cracks, and surface wear. Internal components, including ring and pinions, gears, clutches, and carriers, are meticulously inspected and tested. All bearings and seals are replaced, and gears are checked for optimal tooth contact patterns and correct rolling torque for precise setup and longevity. Proper gear backlash is set to ensure adequate lubrication and quiet operation, while axle tubes are inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-enticed deep cleaning process, which sets a high standard for remanufactured axle assemblies. This particular unit includes the cover but does not come with fluid. The wheelbase for this assembly is 131 inches, and it has a 75 lb axle weight.
