Product Description

The Yukon ZK C9.25-R-B Master Overhaul Kit is a comprehensive differential rebuild kit engineered for 9.25" Chrysler rear axles from 2001 through 2009. It includes OEM-grade Timken/Koyo bearings and races, full shim set, crush sleeve, and all hardware needed for professional-level gear setup. Ideal for Ram, Dakota, Durango, Aspen, and Mitsubishi Raider owners restoring worn differentials or upgrading to performance or limited-slip carriers.

Designed for precision and durability, this kit ensures correct pinion preload and backlash using OE-style components. The included silicone gasket and oil slinger reduce leak risk, while marking compound aids in achieving an optimal gear pattern. The rebuild remains emissions-compliant, maintaining the stock drivetrain setup.

Professional installation recommended: requires torque wrench, dial indicator, pinion depth tool, and hydraulic press for bearing removal. Crush sleeve must be replaced with each install to ensure proper preload. Compatible with all gear ratios and aftermarket carrier types for Chrysler 9.25" housings.
