3.73 Posi Limited Slip Differential Assembly

The Zumbrota Drivetrain RAA435-2162C is a remanufactured complete axle assembly specifically designed for 2004-2008 Dodge Ram 3500 DRW 4x4 models with a 3.73 ratio and Posi Limited Slip Differential. It is compatible with models from 2004-2008, excluding Cab-Chassis models from 2007-2008. Each axle assembly is meticulously rebuilt to the highest quality standards. The process includes thorough inspection of the housing for straightness, cracks, and surface wear, along with 100% inspection and testing of all internal components, including ring & pinions, internal gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are inspected for optimal tooth contact patterns and precise rolling torque is set using inch-pound measurements for longevity. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peening deep cleaning process. This remanufactured assembly ensures precision setup and longevity through correct gear backlash settings for proper lubrication and quiet operation. The 11.5" axle diameter and 3.73 gear ratio are key specifications. This product includes a core charge, which is refundable upon return of the old, salvageable part.
