3.73 Posi Traction Rear Axle Assembly

The Zumbrota Drivetrain RAA435-2310B-P is a remanufactured axle assembly featuring an AAM 11.5-inch ring gear with a 3.73 gear ratio and Posi Traction. This full-floating axle assembly is rebuilt to stringent quality standards, with all internal components thoroughly inspected and tested. Bearings, seals, crush sleeves, pinion nuts, and shims are replaced 100%. Gears are examined for optimal tooth contact patterns and correct rolling torque, with backlash precisely set for lubrication and quiet operation. The axle tubes are inspected and straightened to OEM specifications. Zumbrota employs an exclusive hydro-blast rinse, sandblasting, and proprietary shot-enticed deep cleaning process for superior remanufacturing. This assembly includes the differential cover but does not include hubs, brakes, backing plates, or axle shafts. The fluid capacity is 5.25 quarts, and fluid is not included. The gear ratio is 3.73, and it is designed for regular grade applications. Fitment information indicates this axle is for 2014-2018 Ram 2500 4WD models. It is crucial to verify specific vehicle compatibility before purchase.
