Remanufactured Front Axle Assembly 3.21 Ratio

The Zumbrota Drivetrain RAA440-1470A is a remanufactured front axle assembly crafted with precision and reliability. Zumbrota's remanufacturing process includes a comprehensive inspection and testing of all internal components, such as ring and pinions, gears, clutches, and carriers. To guarantee longevity and smooth operation, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The internal gears are checked for optimal tooth contact patterns, and the rolling torque is precisely set using inch-pound measurements. Gear backlash is carefully adjusted to ensure proper lubrication and quiet operation, while the axle tubes are verified to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting technique on both internal and external parts, followed by a proprietary deep cleaning process. This not only restores an OEM finish but also ensures the component is free from contaminants. Each unit is shipped in high-density plastic totes to prevent damage during transit. This specific axle assembly (RAA440-1470A) is designed for 2013-2018 Ram 1500 4WD models. It features a 215mm IFS C215F differential, an 8.46-inch ring gear, and a 3.21 gear ratio. While primarily fitting 2013-2018 models, some sources indicate compatibility with 2013-2021 Ram 1500 and 2019-early 2021 Ram 1500 Classic models. The product may also be subject to California Proposition 65 warnings regarding cancer and reproductive harm.
