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

25T aluminium pulley for NT1 drivetrain use

This 25-tooth aluminium pulley is supplied as an aftermarket fitment compatible with the XRAY NT1 chassis. Use it as a straightforward replacement or as part of gearing tweaks for 1/10 electric touring car drivetrains.

Changing tooth count or material alters shift response and final ratio; aluminium construction maintains precise tooth form and offers improved wear resistance over softer compounds, aiding consistent engagement during extended sessions. It is designed to integrate with the NT1 drivetrain without altering chassis alignment or the vehicle's electronics.

Fitment advice: mount the pulley in the NT1-position using the chassis retention system already in place. Verify the tooth count and check pinion to spur mesh when installing to avoid misalignment and accelerated wear.
