3.90 Posi-Traction 12-Bolt Cover Differential Assembly

The Zumbrota Drivetrain RAA435-1752C is a remanufactured axle assembly engineered for optimal performance and durability in Chrysler 9.25 inch ring gear applications. This complete axle assembly is rebuilt to exacting standards, featuring a 3.90 gear ratio for enhanced power delivery and posi-traction for improved grip. It is designed with a 12-bolt hexagon cover and is specifically intended for 1994-1997 Dodge Van 3500 models. While it provides the core axle components, it is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. During the remanufacturing process, Zumbrota Drivetrain thoroughly inspects all components. This includes verifying the straightness of axle tubes, checking housings for surface wear and cracks, and performing a 100% inspection of all internal parts such as ring and pinions, internal gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts to ensure longevity and reliable operation. The gears are meticulously set for optimal tooth contact patterns, correct rolling torque, and proper backlash, guaranteeing precise setup, quiet operation, and adequate gear lubrication. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, setting a high standard for remanufactured axle assemblies.
