Description

The Zumbrota Drivetrain RAA435-1655B-P is a remanufactured rear axle assembly meticulously rebuilt for specific GM 14 Bolt trucks. This assembly includes a Posi Limited Slip Differential and a 3.73 gear ratio, making it suitable for 1990-2000 Chevrolet and GMC 2500 and 3500 pickup trucks equipped with the VIN K engine and 4x4 drivetrain. Zumbrota Drivetrain ensures the highest quality in their remanufacturing process. Every axle assembly features tubes straightened to OEM specifications and housings tested for cracks and wear. A comprehensive 100% inspection of all internal parts, such as ring and pinion gears, internal gears, clutches, and carriers, is performed. To guarantee peak performance and durability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housings are then restored to their original OEM finish through a state-of-the-art hydro blasting and rinsing process. Precision setup and longevity are achieved by establishing the correct rolling torque using inch-pound measurements. This axle assembly comes with a refundable core charge of $1,000. This deposit is returned upon receipt of your old, salvageable axle for recycling or rebuilding. For a smooth transaction, please confirm and accept the core charge. Detailed core return instructions are available.
