Description

The Zumbrota Drivetrain RAA435-2307X1 is a remanufactured rear axle assembly, engineered as a direct replacement for GM 9.5 axle housings. This unit features an open differential with a 3.73 gear ratio, providing a standard performance upgrade for the way you drive. All tubes are meticulously inspected and straightened to OEM specifications to guarantee precise fitment and longevity. This rear axle assembly is specifically designed for 2014-2019 GM 1500 Pickup trucks, including the 2019 Classic models. Zumbrota Drivetrain offers aftermarket gear upgrades and custom options such as Limited Slip Differentials and Lockers for owners seeking to tailor their vehicle's performance. Zumbrota Drivetrain is recognized as a standard in remanufacturing performance, ensuring that each axle assembly meets rigorous quality controls. Buyers should be aware of a refundable core charge, which is a deposit for the old part, returned upon receipt of the salvageable core.
