Dana 44 8.5-Inch Ring Gear Electronic Locking Differential

The Zumbrota Drivetrain RAA435-50135 is a remanufactured rear axle assembly engineered for the Dana 44 with an 8.5-inch ring gear and an electronic locking differential. This unit features a 3.36 gear ratio and is specifically designed for 2008-2015 Nissan Titan 4x4 models with a 139.8-inch wheelbase. Zumbrota Drivetrain Axle Assemblies are rebuilt to stringent quality standards, undergoing thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. Crucially, all bearings and seals are replaced, and gears are examined for optimal tooth contact patterns and correct rolling torque, ensuring precise setup and longevity. The assembly also ensures correct gear backlash for proper lubrication and quiet operation. The remanufacturing process includes inspecting axle tubes for OEM specification straightness and utilizing an exclusive hydro-blast rinse and sandblasting procedure, followed by proprietary shot-peening for deep cleaning. This process restores housings to an OEM finish, setting a high standard for axle assembly remanufacturing. Please note that this assembly does not include hubs, brakes, backing plates, or axle shafts. This axle assembly is compatible with 2008-2014 Nissan Titan 4WD models. It is important to confirm that this specific axle assembly is the correct fit for your vehicle's configuration, as it is built to order and may have specific build options to select.
