14 Bolt DRW 4.56 Posi-traction Remanufactured Axle Assembly

The Zumbrota Drivetrain RAA435-1656D-P is a remanufactured axle assembly specifically designed for GM 14 Bolt trucks manufactured between 1990 and 2000. This unit features a 4.56 gear ratio, making it suitable for applications requiring enhanced pulling power or higher RPMs at cruising speeds. It is configured for Dual Rear Wheel (DRW) vehicles and includes a Posi-traction limited-slip differential, but it is not compatible with Wide Track variants. Each Zumbrota remanufactured axle assembly is meticulously rebuilt to meet high standards of precision and reliability. The remanufacturing process involves a comprehensive inspection of all components. Tubes are straightened to OEM specifications, and housings are thoroughly checked for wear and cracks. Internal parts, including the ring and pinion gears, clutch packs, and carrier, are inspected 100%. To ensure optimal performance and durability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housing is then cleaned using a hydro blasting process to achieve an OEM finish, and precise rolling torque is set using inch-pound measurements for longevity. This axle assembly is built to order and typically ships when ready, with options for expedited shipping available at checkout. Zumbrota Drivetrain offers a core charge system, where an upfront deposit is paid and refunded upon the return of your old, salvageable part.
