Description

The Zumbrota Drivetrain Reman Axle Assy is a comprehensively rebuilt rear axle assembly engineered for GM 9.5" applications from 2006-2009, specifically for the Chevrolet Trailblazer. This unit comes equipped with a 4.11 gear ratio, is designed for 6.0L engines, and includes a Posi Limited Slip Differential for enhanced traction and performance. This axle assembly undergoes a rigorous remanufacturing process. All tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks. Internals, including the ring and pinion, gears, clutches, and carrier, are subjected to 100% inspection. Furthermore, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new components to ensure reliability and longevity. The housings are hydro blasted to restore them to their original OEM finish. Precision is paramount in the setup of this axle. Zumbrota Drivetrain establishes the correct rolling torque using inch-pound measurements to guarantee precision setup and extended service life.
