This unit features an 8.8-inch ring gear, a Posi Limited Slip Differential (LSD), and a 3.73 gear ratio, offering a robust upgrade for your drivetrain. Each Zumbrota axle assembly undergoes a meticulous remanufacturing process.

The ring and pinion gears are inspected for optimal tooth contact patterns, and the rolling torque is precisely set in inch-pounds for enhanced performance and a quieter ride. Zumbrota's commitment to quality is evident in their advanced cleaning methods, which utilize hydro-blasting and sandblasting to restore the housing to an OEM finish, providing peace of mind and a visually superior product. The axle tubes are guaranteed to meet OEM standards for straightness.
