This 26-tooth aluminium pulley is a direct-fit replacement for the XRAY NT1 1/10 on-road chassis, providing a tougher, lighter alternative to factory pulleys. It is designed to work with the NT1 spur and pinion arrangement to tweak engagement and drivetrain feedback during tuning.
Typical installation is within the scope of hobby workshops: remove the original pulley, verify bearing seating and shaft alignment, fit the 26T pulley while ensuring correct spur mesh, and secure the fixing hardware without over-tightening. Confirm free rotation and minimal play before a trial run.
Use this pulley as a tuning aid rather than assuming a performance leap. Variations in tooth count or material change mesh feel, noise and wear patterns. Fit this aluminium option to explore reduced flex and alternate durability compared with OEM parts, and make sure your NT1 gear stack and bearings are compatible.
