XRAY NT1 18T 1st gear by Arrowmax AM-NT1-338518  [AM-NT1-338518]

Arrowmax 1st gear for XRAY NT1

This clutch pinion is an RC-scale replacement part manufactured by Arrowmax for the XRAY NT1 platform. Machined from 7075-T6 aluminium and given a hard coating, it is intended to replace the 1st gear pinion and to mesh with the NT1 spur gear without modification.

Available tooth counts cover a range used in on-track tuning, allowing gear ratio changes without altering the motor or gearbox: 16T, 17T, 18T, 19T, 20T, 21T, 22T and 23T. Use the different tooth options to fine-tune acceleration and top speed characteristics on your XRAY NT1 setup.

Installation notes: this pinion is designed to fit the NT1 clutch assembly form factor, so check shaft diameter and clutch fit before final installation. When fitting, ensure clean mesh with the spur gear and verify clutch engagement through a range of throttle inputs to avoid premature wear.

Tuning role: replacing the 1st pinion is a straightforward way to adjust gearing for track conditions, motor characteristics, or driver preference. Paired with standard NT1 spur gears, these pinions serve purely as gearing choices and do not require electronic changes to motor or ESC settings.
