3.42 Posi-Traction Differential Axle Assembly

The Zumbrota Drivetrain RAA435-169A-P is a remanufactured axle assembly, meticulously rebuilt to the highest quality standards for precision and reliability. Each assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are fully inspected and tested. Crucially, all bearings and seals are replaced, and gears are checked for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precise setup and longevity. Proper gear backlash is set to ensure adequate lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, setting a high standard for axle assembly remanufacturing. The axle tubes are inspected and straightened to OEM specifications, and housings are tested for wear and cracks. This specific assembly is designed for 2009 Dodge Ram 2500 and 3500 models. It features an AAM 11.5-inch ring gear, a 3.42 gear ratio, Posi-Traction (limited-slip differential), and is for Single Rear Wheel (SRW) and 2WD configurations.
