The Zumbrota Drivetrain RAA435-1657C is a remanufactured axle assembly engineered as a direct replacement for specific GM 14 Bolt Truck models manufactured between 1990 and 2000. This assembly is built to exacting OEM specifications, ensuring reliable performance and longevity. This axle assembly features a 4.10 gear ratio with a 10.5-inch ring gear. It is designed for Dual Rear Wheels (DRW) applications and includes the Wide Trac Option GTY and Ratio Option GT5. Importantly, this configuration is Without Posi Traction. The housing undergoes a rigorous inspection process, including checks for straightness, surface wear, and cracks. All internal components, such as ring and pinion gears, internal gears, clutches, and carriers, are inspected 100%. Critical wear items like bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housing is also hydroblasted and rinsed to restore an OEM finish, and correct rolling torque is established for precision setup and longevity. Note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. The product is built to order and subject to a refundable core charge of $1,000. Free shipping is available on orders over $199, with a flat rate of $299 for all reman parts.
