Precision 18-Tooth first gear for XRAY NT1

Replace or upgrade your XRAY NT1 first gear with the Arrowmax AM-NT1-338518, an 18-tooth unit machined from 7075-T6 aluminium to keep mass low while offering solid durability. It is engineered to pair cleanly with spur gears for reliable power delivery.

Consistent performance with a protective finish

The hard-coated treatment on the AM-NT1-338518 helps protect against surface wear so the gear retains its shape and engagement characteristics over many runs. Proper mesh adjustment will maximise the smoothness and response of your drivetrain.

Tuning range from 16T to 23T

Arrowmax supplies this clutch pinion range from 16T up to 23T so you can tune acceleration and top speed according to circuit style and motor setup. Changing pinions is a straightforward way to alter your gear ratio for session tuning.

Will the AM-NT1-338518 bolt straight onto standard NT1 clutches?

It is designed to fit NT1 clutch assemblies, but inspect your clutch for wear and confirm the mounting fasteners are correct before final fitting.

How do I check proper gear mesh with this pinion?

Fit the pinion, rotate the drivetrain slowly, and set a consistent gap so teeth engage smoothly without binding or excess play. Adjust shims if needed.

Are there benefits to choosing a higher tooth count?

A higher tooth count raises top speed at the expense of some acceleration, which can help on faster tracks where top end matters.

Should I use a different pinion for a higher torque motor?

Torque-heavy motors may benefit from slightly lower gearing to reduce strain on the drivetrain; pick a lower tooth count if you notice excessive load or slipping.
