Remanufactured Complete Axle Assembly 4.10 Ratio SRW

The Zumbrota Drivetrain RAA435-1661C is a remanufactured complete axle assembly designed for GM 14 Bolt trucks manufactured between 1990 and 2000, specifically for the 2500 and 3500 Pickup models. This assembly comes with a 4.10 gear ratio, is configured for 2WD vehicles, and is a Single Rear Wheel (SRW) unit, featuring a 14-bolt pattern. During the remanufacturing process, Zumbrota Drivetrain meticulously inspects and tests all internal components, including ring and pinions, internal gears, clutches, and carriers. To ensure optimal performance and durability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are thoroughly inspected for proper tooth contact patterns and correct rolling torque, with backlash precisely set to guarantee adequate gear lubrication and quiet operation. Zumbrota employs a rigorous cleaning process that includes hydro-blasting and sandblasting, followed by a proprietary shot-peening deep cleaning procedure. This ensures that housings meet OEM standards for straightness and are tested for surface wear and cracks. This comprehensive approach sets a high standard for remanufactured axle assemblies.
