Second gear upgrade for NT1 transmission

This Arrowmax AM-NT1-338520 second gear is made for the XRAY NT1 gearbox, supplying a direct-fit 20-tooth option when a 20T second gear is needed. Machined from 7075-T6 aluminium with a hard coating, the part is specified to keep contact with NT1 spur gears precise and consistent during normal on-track racing use.

Install this gear when adjusting final drive ratios or replacing a worn NT1 second gear. The hardened aluminium construction balances low mass with surface durability, and the tooth profile is cut to match XRAY NT1 spur gears to minimise noise and preserve repeatable mesh under load.

  • Compatibility: XRAY NT1 transmissions requiring a 2nd gear 20T.
  • Material note: 7075-T6 aluminium with hard coating for improved surface life.
  • Available tooth counts nearby: 16T to 23T variants for fine ratio tuning.

Will this replace the NT1 stock 2nd gear without modification?

Yes. This 20T unit is produced to the XRAY NT1 second gear profile for direct replacement and typically fits the gearbox without extra machining.

How does the hard coating change wear and noise?

The hard coat increases surface toughness to resist scuffing and pitting while keeping weight low, which helps maintain a quieter and more consistent mesh compared with untreated aluminium.

Can I use this gear to alter gear ratios on track?

Yes. Arrowmax supplies similar 2nd gears across the 16T-23T range so you can select different tooth counts for fine tuning final drive and acceleration characteristics.
