Gear diffs are popular in touring car racing because they provide consistent, predictable handling characteristics across different track conditions.

The 38 tooth pulley is part of XRAY's precision drivetrain system, ensuring proper gear mesh and efficient power delivery to your rear wheels.

Installation is straightforward for anyone familiar with touring car maintenance. The diff case fits cleanly into the X4 2026's universal bulkhead design, and everything you need for the differential assembly is included in the package. Whether you're building a new chassis or upgrading your existing setup, this composite gear diff provides the foundation for consistent rear end performance on the track.
