3.55 5-Lug Posi Limited Slip Differential Assembly

The Zumbrota Drivetrain RAA435-1921B-P is a remanufactured axle assembly engineered for Chrysler 8.25-inch rear ends, specifically designed for 1998 and 1999 Dodge B1500 and B2500 vans. This axle assembly is rebuilt to the highest quality standards, ensuring precision and reliability. It features a 3.55 gear ratio, 5-lug axles, a Posi Limited Slip Differential for enhanced traction, and a 10-bolt cover. Zumbrota meticulously inspects all internal components, including ring and pinions, clutches, and carriers. All bearings and seals are replaced, and gears are examined for optimal tooth contact patterns and correct rolling torque to ensure precise setup and longevity. Proper gear backlash is set for correct lubrication and quiet operation. Zumbrota's remanufacturing process includes rigorous inspection of axle tubes for OEM standards of straightness, as well as testing housings for surface wear and cracks. The internal and external parts undergo an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process, setting a high standard for axle assembly remanufacturing. This unit includes the cover but does not include fluid.
