3.73 Posi Limited Slip Differential

The Zumbrota Drivetrain RAA435-1840B-P is a remanufactured axle assembly engineered for GM 9.5" rear differentials, specifically for 1995-1999 GM Suburban 1500 models with 2WD and 8-lug configurations. This assembly includes a Posi Limited Slip Differential and a 3.73 gear ratio. Zumbrota Drivetrain emphasizes quality and reliability in its remanufacturing process. Each axle assembly is subjected to rigorous inspection for structural integrity, including checks for straightness, cracks, and surface wear on the housing. Internally, all components such as ring and pinions, gears, clutches, and carriers are fully inspected and tested to meet high standards. To guarantee longevity and performance, 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 established using inch-pound measurements for setup and durability. Furthermore, Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-peened deep cleaning process. This comprehensive cleaning method ensures the housing is restored to an OEM finish, setting a benchmark for remanufactured axle assemblies. The assembly includes the cover, but fluid is not included. This specific axle assembly is designed for 1995-1999 Chevrolet C1500 Suburban Base RWD and 1995-1999 Chevrolet C1500 Suburban LS RWD models, featuring a 3.73 ratio, 2WD, and 8-lug configuration with a Posi Limited Slip Differential.
