Remanufactured Axle Assembly, 3.90 Ratio 4x4

The Zumbrota Drivetrain RAA435-1783C-P is a remanufactured rear axle assembly engineered for the 1994-1999 Dodge Ram 2500 4x4, specifically those equipped with staggered shocks and a Posi Limited Slip Differential (LSD). This assembly features a 3.90 gear ratio and a Chrysler 9.25-inch ring gear. Each axle assembly is rebuilt to stringent quality standards by Zumbrota Drivetrain. The process includes a comprehensive inspection of all tubes for straightness, and housings are tested for surface wear and cracks. Internally, every component—including the ring and pinion gears, internal gears, clutches, and carriers—is subjected to a 100% inspection. To ensure peak performance and durability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are meticulously set for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precision, which contributes to longevity and quiet operation. Backlash is also precisely set to ensure proper gear lubrication and a smooth, quiet experience. Zumbrota Drivetrain employs an advanced cleaning process for its remanufactured assemblies. Housings undergo a state-of-the-art hydro-blast and rinsing procedure, followed by sandblasting and a proprietary shot-enticed deep cleaning. This multi-step cleaning ensures the cases are restored to an OEM finish, setting a high standard for remanufactured axle assemblies. Key specifications for this unit include a semi-floating axle type, a 3.90 gear ratio, and the inclusion of a differential cover. It does not come with fluid.
