9.25-Inch 3.55 Ratio 12-Bolt Rear Axle Assembly

This unit features a 9.25-inch Chrysler ring gear and a 3.55 gear ratio, tailored for 4x2 drive configurations. It comes equipped with a Posi Traction limited-slip differential for enhanced grip and performance. This axle assembly is rebuilt with a strong emphasis on quality and longevity. Zumbrota Drivetrain inspects all tubes to ensure they meet OEM straightening specifications and rigorously tests housings for surface wear and cracks. A comprehensive 100% inspection of all internal parts, including gears and carriers, is performed. To guarantee performance and durability, all bearings, seals, pinion nuts, and shims are replaced. The housing is then meticulously cleaned using a state-of-the-art hydro blasting process, returning it to its original OEM finish. Precision setup is confirmed by establishing correct rolling torque with inch-pound measurements. This specific axle assembly is noted to fit Chrysler 9.25 inch applications for the 1994 Ram 2500 with a 3.55 ratio, 2WD, and Posi Traction, up to September 23, 1993. It is crucial to note that this assembly is sold as the axle housing and internal components only; it does not include hubs, brakes, backing plates, or axle shafts.
