20-tooth second gear for NT1 kits

This Arrowmax AM-NT1-338520 20T second gear is produced for the XRAY NT1 transmission and provides a direct-fit option when a 20-tooth second gear is required. Manufactured from 7075-T6 aluminium with a hard coating, the component helps keep contact with NT1 spur gears accurate and steady during competitive use.

Use this gear for ratio tweaks or when swapping out a tired NT1 second gear. The hardened aluminium keeps mass down while improving resistance to surface wear, and the tooth geometry is intended to match XRAY NT1 spur gears to lower noise and keep mesh repeatable under load.

  • Compatibility: For XRAY NT1 transmissions using a 2nd gear 20T.
  • Material note: 7075-T6 aluminium with a hard surface treatment for durability.
  • Ratio choices: Other tooth counts offered in the 16T to 23T range for tuning.

How should I set spur mesh with this gear?

Set mesh by positioning the spur and second gear with a small tooth-to-tooth clearance, then tighten and test under load. Recheck after a short run to confirm the hard-coated aluminium beds in correctly.

Will this reduce drivetrain noise?

The precise tooth profile and hard-coated surface are intended to improve contact accuracy and can lower gear whine compared with improperly matched or worn stock gears.

Are there lighter or heavier options available?

This aluminium 7075-T6 item is chosen for a balance of lightness and strength. For ratio changes you can select other tooth counts from Arrowmax in the 16T-23T spread rather than switching material weight classes.
