The XRAY 355718 - 18T pinion gear focuses on reliable high speed performance for larger circuit layouts. Special steel construction and precision-cut teeth help reduce wear while keeping gear engagement smooth under load.
Precision tolerances ensure the pinion runs concentric and minimizes wobble. That high level of manufacturing control helps maintain predictable handling and reduces the chance of premature gear damage.
When track sections demand higher gearing, this pinion helps the XB8E reach efficient top speed while preserving driveability. The supplied M4x4 set screw secures the gear in place during aggressive runs.
