This 26T aluminium pulley is supplied as a direct replacement for the XRAY NT1 1/10 on-road chassis and provides a stiffer, lighter alternative to stock parts. It mates with the NT1 spur and pinion arrangement to alter engagement feel and tuning response.
Installation is a routine hobbyist task: remove the factory pulley, confirm bearing fit and shaft alignment, slide the 26T unit into position while maintaining proper mesh with the spur, and secure fasteners with appropriate torque. Check for free rotation and minimal side play before running the car.
Think of the pulley as a tuning item rather than a guaranteed speed upgrade. Different materials or tooth counts change how the drivetrain sounds and responds. Fit this aluminium pulley when you want to evaluate reduced flex or alternate wear rates versus original parts, and always verify compatibility with NT1 gear and bearing sizes.
