Complete Axle Assembly 4.10 Ratio 6-Lug

The Zumbrota Drivetrain RAA435-212E-P is a meticulously remanufactured complete axle assembly, specifically designed to meet the rigorous demands of the 2011 Ford F-150. This unit features a 4.10 gear ratio and is built around a robust Ford 9.75-inch ring gear, ensuring reliable power transfer. It is equipped with 6-lug axles and a Posi Traction limited-slip differential for enhanced traction and performance. Each Zumbrota axle assembly is rebuilt to the highest quality standards. The process involves thorough inspection of the housing for straightness, cracks, and surface wear, with all tubes straightened to OEM specifications. Internal components, including ring and pinions, internal gears, clutches, and carriers, undergo a 100% inspection. To ensure longevity and precision, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, with backlash set precisely for proper lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peening deep cleaning process, setting a high standard for axle assembly remanufacturing. This axle assembly does not include hubs, brakes, or backing plates, and axle shafts are also not included. Buyers should confirm specific fitment details for their vehicle application.
