XRAY NT1 1st Gear 18T Pinion - Arrowmax AM-NT1-338518  [AM-NT1-338518]

Arrowmax 1st gear pinion for NT1 racing

This Arrowmax clutch pinion is an aftermarket replacement tailored for the XRAY NT1 chassis. It is CNC machined from 7075-T6 aluminium and receives a hard coating to improve surface durability while maintaining accurate tooth profiles for direct mesh with NT1 spur gears.

Tooth options include common tuning steps: 16T, 17T, 18T, 19T, 20T, 21T, 22T and 23T. Swap between these counts to refine acceleration and top speed without modifying the motor or gearbox.

Fitment advice: the pinion is made to the NT1 clutch form factor, so check shaft dimensions and clutch compatibility before fitting. Ensure the gear mesh is set correctly and confirm clutch engagement through real-world throttle ranges to avoid increased wear.

Tuning notes: changing the 1st pinion is a direct way to alter drive characteristics for different tracks or driver style. When used with standard NT1 spur gears, the pinion acts only as a gearing adjustment and should not force electronic changes.
