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

19-tooth aluminium pulley designed for NT1

This 19T aluminium pulley is supplied as a direct-style replacement for the XRAY NT1 touring car belt system, intended to adjust pulley engagement and belt routing while preserving the original chassis layout. The component mirrors the OEM form factor with a 19-tooth profile in aluminium material.

Fitting is straightforward when swapping the stock pulley on an NT1 drivetrain since it installs in the same location and follows the NT1 belt path. After installation, verify alignment and belt tension to reduce wear, and ensure the pulley seat and fasteners are compatible with the original hardware before final tightening.

In terms of setup, changing tooth count or pulley material alters rotating mass and belt geometry at drivetrain scale, which can influence belt tension and how the car delivers power out of corners. Use this pulley as part of measured setup changes rather than expecting a single change to solve handling issues.

For drivers seeking a 19T aluminium direct replacement for XRAY NT1 belt systems, XN1-41 provides a simple tuning option to modify drivetrain engagement while keeping the stock arrangement.
