The 3Racing XN1-43/RE aluminum pulley is engineered to fit the Team XRAY NT1 chassis with tight tolerances, giving a reliable match and consistent operation. This 25-tooth component uses aircraft-grade style aluminum for reduced weight and increased longevity compared with stock plastic parts. Fitting this pulley smooths power delivery and helps limit drivetrain wear, making it a practical upgrade for racers chasing consistent lap times.
Aluminum pulleys strike a good balance between strength and low mass, which reduces rotational inertia. The 3Racing XN1-43/RE helps the car accelerate more quickly and respond faster to throttle inputs, benefits that are particularly noticeable on tight technical tracks.
Before installing the 3Racing pulley, clean the shaft and mating surfaces to remove grit. Secure the pulley to the specified torque but avoid over-tightening to prevent thread or part damage. Inspect the pulley after heavy runs and service as needed to maintain reliable performance.
