9.25" Rear Axle Assembly 3.55 Posi-Traction

The Zumbrota Drivetrain RAA435-123A-P is a remanufactured 9.25-inch rear axle assembly specifically engineered for 2006-2008 Dodge Ram 1500 vehicles. This unit is equipped with a 3.55 gear ratio and a Posi-Traction (Limited Slip Differential) for enhanced 4WD performance. This includes straightening axle tubes to OEM specifications and thorough testing of housings for surface wear and cracks. A comprehensive 100% inspection of all internal parts, such as ring and pinion gears, clutch packs, and carriers, is conducted. Furthermore, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new components to guarantee optimal performance and durability. The housings are cleaned using a hydro-blasting process to achieve an OEM finish, and correct rolling torque is meticulously set using inch-pound measurements for precision and extended lifespan. This axle assembly is built to order and includes a refundable core charge. Please confirm and accept the core charge of +$1,500, which will be refunded upon return of your old, salvageable part for recycling or rebuilding. Core return instructions are available on the Zumbrota Drivetrain website.
