The Koyo bearings included in this kit are a solid choice, offering reliable performance and longevity. This package contains the essential components needed for a differential gear change, ensuring you have the right parts for the job.

When undertaking a gear change like this, it's important to have the correct installation tools and a service manual for your specific Jeep Cherokee XJ. Proper setup and break-in procedures are critical for the longevity of your new gears. This kit is a comprehensive solution for those looking to re-gear their rear differential for improved performance and drivability.
