Description

The Zumbrota Drivetrain Reman Axle Assy is a comprehensively remanufactured rear axle assembly engineered for specific Chrysler 9.25" applications. This unit is built to order and ensures quality through a multi-step inspection process. All tubes are verified for straightness and structural integrity, with housings tested for wear and cracks. Internally, every component receives a 100% inspection, including the Ring & Pinion gears, internal gears, clutches, and carrier. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housing is meticulously cleaned using a state-of-the-art hydro blasting process to restore its OEM finish. Precision setup is confirmed with correct rolling torque established using inch-pound measurements. This specific axle assembly features a 3.55 gear ratio, a 9.25-inch ring gear, and a 12-bolt hexagon cover, designed for 4x2 Posi Traction (Limited Slip Differential) configurations. It is explicitly stated that this assembly does not include hubs, brakes, backing plates, or axle shafts, and is intended for 2002-2005 Dodge D1500 models, excluding the SRT-10. Compatibility is limited to 2WD models.
