GM 2500 Posi Semi-Float Rear Axle Assembly

The Zumbrota Drivetrain RAA435-1524D is a remanufactured complete axle assembly engineered for 1989-2000 GM 2500 trucks. It is built to stringent quality standards, ensuring precision and reliability. This axle assembly features a robust 9.5-inch ring gear, a 4.56 gear ratio for enhanced pulling power, and a Posi limited-slip differential (LSD) for improved traction. It is designed for vehicles with 8-lug wheels and uses a semi-float axle configuration. During the remanufacturing process, Zumbrota Drivetrain meticulously inspects all components. This includes thorough examination of axle tubes for straightness, as well as checking housings for surface wear and cracks. Every internal part, such as ring and pinions, internal gears, clutches, and carriers, undergoes a 100% inspection. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced to ensure optimal performance and longevity. The gear setup is precisely established using inch-pound measurements for correct rolling torque and backlash, promoting proper gear lubrication and quiet operation. Zumbrota Drivetrain utilizes an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process, setting a high standard for axle assembly remanufacturing and restoring components to an OEM finish.
