Dana 60 4.30 Ratio Front Axle Assembly

The Zumbrota Drivetrain RAA434-127E is a remanufactured Dana 60 front axle assembly, precision-rebuilt to the highest quality standards for reliability. Each assembly undergoes thorough inspection for straightness, cracks, and surface wear. Internal components, including ring and pinions, gears, and clutches, are fully inspected and tested. All bearings and seals are replaced. This axle assembly features a 9.75-inch ring gear diameter and a 4.30 gear ratio, designed for optimal tooth contact patterns and precise setup for longevity. Correct gear backlash is set to ensure proper lubrication and quiet operation. The axle tubes are inspected to meet OEM standards for straightness. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peening deep cleaning process. This specific unit is designed for 2011-2012 Ford F350 DRW Cab Chassis models with a 4.30 ratio. The axle assembly includes the cover. However, it does not include fluid or mounting hardware, which must be sourced separately.
