GM 9.5-inch 3.73 Posi Limited Slip Axle Assembly

The Zumbrota Drivetrain RAA435-2252A-P is a remanufactured axle assembly specifically designed for GM 9.5-inch rear ends. This unit comes equipped with a 3.73 gear ratio and a Posi Limited Slip differential, enhancing traction and performance. Each Zumbrota Axle Assembly is rebuilt to rigorous quality standards, undergoing thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are meticulously inspected and tested. To ensure longevity and quiet operation, all bearings and seals are replaced, and gears are set to precise backlash specifications using inch-pound measurements for optimal tooth contact patterns and rolling torque. The axle tubes are also inspected to meet OEM straightness standards. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process on both internal and external parts. This advanced cleaning method sets a high standard for axle assembly remanufacturing. This specific assembly is designed for 2006-2007 GMC 1500 models featuring a 6-lug semi-floating axle and a 14-bolt cover. The cover is included with the assembly, but it does not come with differential fluid.
