Description

The Zumbrota Drivetrain RAA435-10075C is a remanufactured rear axle assembly engineered for specific GM 2500 and 3500 trucks from the 2020-2022 model years. This unit is designed for Single Rear Wheel (SRW) applications and comes with a 3.42 gear ratio, utilizing the AAM 11.5-inch ring gear and the GU6 ratio option. This particular axle assembly is configured as an 'open' differential, meaning it does not include the G80 Posi Traction feature. It is crucial for buyers to be aware that this assembly does not come with hubs, brakes, backing plates, or axle shafts, which must be sourced separately if not already present or transferred from the original axle. As a remanufactured component, Zumbrota Drivetrain rebuilds these assemblies to high standards of precision and reliability. The product is built to order, with shipping times varying. A refundable core charge of $2,000 applies, which is returned upon receipt of the old, salvageable axle for recycling or rebuilding, following the provided core return instructions.
