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

25T Aluminum Pulley for XRAY NT1

This 25-tooth aluminum pulley from 3Racing is presented as a direct-fit RC-scale drivetrain part for the XRAY NT1 chassis. It serves as a straightforward replacement or upgrade where a 25T pulley is required, and is intended for use in 1/10 electric touring car drivetrains.

Material choice and tooth count influence shifting response and final gearing; aluminium construction provides consistent tooth geometry and durability compared with softer materials. The part is intended to integrate with the NT1 drivetrain layout without altering chassis geometry or electronic components such as ESC or motor.

Installation notes: the pulley is installed in the drivetrain location specified by the NT1 layout and uses the existing mounting and retention method on that chassis. Confirm tooth count and mesh when fitting to the spur and pinion to maintain correct engagement and to avoid excess wear.
