Remanufactured Rear Axle Assembly 4.10 Ratio DRW G80 Posi

The Zumbrota Drivetrain RAA435-1658C is a remanufactured rear axle assembly specifically engineered for GM 14 Bolt trucks manufactured between 1990 and 2000. This unit is built to stringent quality standards, ensuring precision and reliability for your drivetrain. This axle assembly boasts a 4.10 gear ratio and is designed for dual rear wheels (DRW) with a straight frame configuration. It comes equipped with the G80 Posi Traction unit for enhanced traction, but excludes hubs, brakes, backing plates, and axle shafts. The remanufacturing process involves thorough inspection of all components, including ring and pinions, internal gears, clutches, and carriers. All bearings and seals are replaced, and gears are inspected for optimal tooth contact patterns and correct setup for longevity and quiet operation. Zumbrota Drivetrain utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process on both internal and external parts. This meticulous cleaning process restores cases to an OEM finish. Axle tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks, ensuring the highest quality rebuild.
