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

19T aluminium pulley made for NT1 belt systems

This 19-tooth aluminium pulley is intended as an aftermarket replacement that fits the XRAY NT1 touring car belt arrangement, allowing users to alter engagement timing and belt routing while retaining the OEM footprint. The pulley keeps the required 19T tooth count in an aluminium finish.

Replacement onto the NT1 drivetrain is simple when the aftermarket pulley matches the stock mounting points; fit it where the original pulley sits and line up the belt path. Once installed, double-check belt alignment and tension and confirm that the pulley seat and fasteners are correct before final tightening.

Changing to a different tooth count or material affects rotating mass and belt geometry at the drivetrain level, which can change belt tension and the car's on-track feel during acceleration and corner exits. Consider this part as one tuning option among others during setup work.

For hobbyists wanting a direct 19T aluminium swap for XRAY NT1 belt systems, XN1-41 delivers a straightforward option to shift drivetrain engagement characteristics while maintaining the original layout.
