Front Axle Assembly 4.30 Ratio Open Differential

The Zumbrota RAA434-111X1 is a ZPA (Zumbrota Performance Axle) front axle assembly engineered for Chrysler 9.25 differentials, specifically for 2007-2008 Ram 1500 Mega Cab models. It comes with a 4.30 gear ratio and an open differential, designed to meet the demands of lifestyles requiring stronger traction, higher speeds, and heavier towing capabilities. Each axle assembly undergoes a rigorous rebuilding process to ensure precision and reliability. This includes thorough inspections for straightness, cracks, and surface wear on all components. Internal parts like ring and pinions, gears, clutches, and carriers are fully inspected and tested. To guarantee optimal setup and longevity, all bearings and seals are replaced, and gear tooth contact patterns are inspected for correct rolling torque. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This meticulous cleaning sets a high standard for axle assembly remanufacturing. The assembly is not pre-filled with oil.
