8.8-Inch Rear Axle Assembly with Posi Limited Slip Differential

The Zumbrota Drivetrain RAA435-1931K-P is a remanufactured axle assembly engineered for 1999-2005 Ford Ranger models. This unit is built around a robust Ford 8.8-inch ring gear and comes with a 4.10 gear ratio, providing enhanced performance for various driving conditions. It incorporates a Posi Limited Slip Differential for improved traction and features 10-inch drum brakes and 28 spline axles for reliable stopping power and durability. Each Zumbrota Drivetrain Axle Assembly undergoes a comprehensive remanufacturing process focused on precision and reliability. The assembly is meticulously inspected for straightness, cracks, and surface wear. Critical internal components, including the ring and pinion gears, clutch packs, and carrier, are thoroughly examined and tested. To ensure optimal performance and longevity, all bearings and seals are replaced, and the gears are set with precise backlash and rolling torque specifications, verified using inch-pound measurements. This attention to detail contributes to proper gear lubrication and quiet operation. The remanufacturing process also includes rigorous inspection of axle tubes for OEM standards of straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning method. This multi-stage cleaning process sets a high standard for remanufactured axle assemblies, ensuring cleanliness and readiness for installation. This axle assembly includes the differential cover, but the differential fluid is not included and must be purchased separately. It is designed for semi-floating axle types and is specifically built for the Ford 8.8-inch rear end. The product is identified by Hollander Number 435-1931K-P. It is crucial to verify fitment with your specific vehicle's tag, as indicated in the product title (*Check Tag*), to ensure compatibility.
