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

19T aluminum pulley for XRAY NT1

This 19-tooth aluminum pulley is offered by 3Racing for use with the XRAY NT1 touring car drivetrain as specified in the product name, intended as an RC-scale replacement part to alter pulley engagement and belt routing. The part is presented as an aluminum pulley with a 19T tooth count, suitable where the OEM pulley form factor is required.

Fit and installation are straightforward when replacing the stock pulley on an XRAY NT1 drivetrain, the pulley mounts in the same location and aligns with the NT1 belt path. Confirm alignment and belt tension after installation to avoid premature wear, and verify that the pulley seat and fasteners match the original hardware before final tightening.

In tuning terms, swapping to an alternate tooth count or a different pulley material changes rotational mass and belt geometry at the scale of the drivetrain, which can influence belt tension and the drivetrain's feel during acceleration and on corner exits. Use this part as one element of incremental setup changes rather than as a single solution.

For users running XRAY NT1 cars who want a direct aluminum replacement pulley in a 19T configuration, this 3Racing XN1-41 part provides a simple option to alter the drivetrain's engagement characteristics while keeping the original layout.
