GM 9.5-inch Axle Assembly 4.10 Posi Limited Slip

The Zumbrota Drivetrain RAA435-1956C-P is a remanufactured complete axle assembly engineered for precision and reliability in GM 9.5-inch axle applications. This unit comes equipped with a 4.10 gear ratio and a Posi Limited Slip Differential, designed to enhance traction and performance. It is specifically configured for vehicles with 8-lug wheels and semi-float C-clip style axles. Every Zumbrota Drivetrain axle assembly undergoes a rigorous remanufacturing process. This includes thorough inspection of the housing for straightness, cracks, and surface wear, ensuring it meets OEM specifications. All internal components, such as ring and pinions, internal gears, clutches, and carriers, are subjected to 100% inspection and testing. Furthermore, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced as standard practice. The gear setup is meticulously performed, focusing on optimal tooth contact patterns, correct gear backlash for lubrication and quiet operation, and precise rolling torque established using inch-pound measurements for longevity and setup accuracy. Zumbrota employs an exclusive cleaning procedure that involves hydro-blasting and sandblasting, followed by a proprietary shot-enticed deep cleaning process. This comprehensive approach sets a high standard for axle assembly remanufacturing, ensuring a like-new finish and performance. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. This specific axle assembly is configured for GM 9.5-inch, 14-bolt applications from 2001-2005 models with the GT5 ratio option. It is designed without the Quadrasteer system and includes Posi Traction.
