XRAY NT1 19T Aluminium Pulley Upgrade XN1-41 by 3Racing  [XN1-41]

19-tooth aluminium pulley for the NT1 drivetrain

This 19-tooth aluminium pulley serves as a direct replacement option for the XRAY NT1 touring car belt system, intended to adjust pulley engagement and belt routing while maintaining the original chassis arrangement. The pulley matches the OEM footprint and carries a 19T tooth profile in aluminium.

Installing the pulley follows the stock location on the NT1 drivetrain and aligns with the existing belt path. After fitting, verify belt alignment and tension, and confirm the pulley seat and fasteners are compatible with the original hardware before applying final torque.

In tuning terms, switching tooth counts or pulley materials alters rotating mass and belt geometry on the drivetrain, which can influence belt tension and how the car behaves through acceleration and corner exits. Use this item as part of incremental setup changes rather than expecting it to be a single cure-all.

For enthusiasts wanting a 19T aluminium direct swap for XRAY NT1 belt systems, XN1-41 provides a simple way to tweak engagement characteristics while preserving the stock layout.
