The Zumbrota Drivetrain RAA435-275B is a remanufactured axle assembly built to high standards of precision and reliability, designed for 2011-2014 Chevrolet Silverado 3500 and GMC Sierra 3500 models with single rear wheels. This assembly features an AAM 11.5-inch ring gear and a 4.10 gear ratio, specified as GT5 option and without Posi-Traction. Each axle assembly undergoes a thorough inspection process, including checks for straightness, cracks, and surface wear.

Gear backlash is set precisely to ensure proper lubrication and quiet operation. The axle tubes are also inspected to meet OEM standards for straightness. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process on both internal and external parts, setting a high standard for remanufacturing. This axle assembly is confirmed to fit 2011-2014 Chevrolet Silverado 3500 and 2011-2014 GMC Sierra 3500 Single Rear Wheel (SRW) models. It is crucial to verify fitment for your specific vehicle, as the product pages indicate that selections outside of these specified applications will not fit.
