XRAY NT1 Aftermarket 25T Pulley XN1-43/RE by 3Racing  [XN1-43/RE]

25-tooth aluminium pulley for XRAY NT1 drivetrains

This 25T aluminium pulley is offered as an aftermarket replacement compatible with the XRAY NT1 chassis. It is suitable as a direct swap or as part of drivetrain tuning where a 25T pulley is needed for 1/10 electric touring cars.

Tooth count and material change the drivetrain's response and final ratio; aluminium ensures consistent tooth geometry and improved longevity versus softer pulley materials, helping to keep mesh stable across runs. The part is intended to sit within the NT1 drivetrain arrangement without modifying chassis geometry or electronics components.

Installation guidance: position the pulley in the NT1-designated location and use the existing mounting hardware. Always confirm the tooth count and final mesh against your spur and pinion to avoid poor engagement or excess wear.
