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

25T aluminium pulley designed for the NT1 drivetrain

This 25-tooth aluminium pulley is supplied as an aftermarket part compatible with the XRAY NT1 chassis. It functions as a direct replacement or upgrade option where a 25T pulley is required in 1/10 electric touring car drivetrains.

Tooth count and material selection influence shift behaviour and final gearing; aluminium preserves tooth profile and provides better wear resistance than softer options, supporting steady mesh across sessions. The component is intended to fit within the NT1 drivetrain layout without altering chassis geometry or the vehicle's electronic setup.

Fitting notes: install the pulley in the NT1-specified location using the existing mounting and retention arrangement. Verify the tooth count and check pinion to spur mesh during assembly to ensure correct engagement and to prevent uneven wear.
