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

19-tooth aluminum pulley for NT1 drivetrains

This 19-tooth aluminum pulley is a drop-in style replacement for the XRAY NT1 touring car belt system, intended to change pulley engagement and belt routing without altering the original layout. The component keeps the OEM form factor while providing the reduced rotating mass and material characteristics of aluminum where a 19T tooth count is required.

Installation follows the stock pulley location on the NT1 drivetrain and uses the same mounting points. After fitting, confirm pulley alignment and belt tension to prevent premature wear, and check that the pulley seating and fasteners match the original components before final torqueing.

From a setup perspective, moving to a different tooth count or to an aluminum pulley shifts small amounts of rotational mass and belt geometry, which can subtly change driveline tension and the car's response under acceleration and through exits. Treat this part as one tuning variable among others when refining handling.

For racers and hobbyists wanting a straightforward 19T aluminum replacement for XRAY NT1 belt systems, the XN1-41 offers a simple way to alter engagement characteristics while maintaining the stock layout.
