Dana 80 Axle Assembly 4.10 Ratio

The Zumbrota Drivetrain RAA435-1788 is a remanufactured Dana 80 axle assembly, meticulously rebuilt to restore your 1994-1995 Dodge Ram 3500 Cab Chassis to its optimal condition. This unit features a 4.10 gear ratio and an 11.25-inch ring gear diameter, secured by a 10-bolt cover. It is specifically configured for models with staggered shocks. Each Zumbrota axle assembly undergoes a comprehensive inspection process. This includes checking for straightness, cracks, and surface wear on housings. All internal components, such as ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. To ensure reliability and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are precisely set for optimal tooth contact patterns and correct rolling torque using inch-pound measurements, and proper gear backlash is established for adequate lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-peened deep cleaning process, setting a high standard for axle assembly remanufacturing.
