Dana 60 Front Axle Assembly 3.55 Ratio

The Zumbrota Drivetrain RAA434-128B is a remanufactured Dana 60 front axle assembly designed for precise fitment and reliable performance. This axle assembly is rebuilt to exacting standards, featuring a 3.55 gear ratio and a 9.75-inch ring gear, specifically for 2011-2012 Ford F-250 and F-350 models equipped with Single Rear Wheels (SRW) and without a wide track setup. Every unit undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are fully inspected and tested. To ensure longevity and quiet operation, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced, and critical measurements like rolling torque and gear backlash are meticulously set. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process for both internal and external parts, setting a high standard for remanufactured axle assemblies. This comprehensive remanufacturing process aims to restore the assembly to OEM specifications for straightness and finish. It is important to note that this assembly includes the main housing and all internal components only. Axles, ball joints, spindles, steering components, and brakes are not included and must be sourced separately.
