Durable 2nd Gear for the NT1 Chassis

Arrowmax AM-NT1-338522 is a replacement 2nd gear produced for use with XRAY NT1 vehicles. The gear is manufactured from 7075-T6 aluminium and finished with a hard coat to give improved resistance to wear versus untreated alloys. This listing covers the 22T variant; other tooth counts are available for tuning the final drive.

The component is intended for the clutch/pinion location and is profiled to match NT1 spur gear geometry. Installation mirrors the standard XRAY NT1 2nd. gear swap process and uses the original mounting components to secure the part.

Tuning tip: altering the tooth count will tweak acceleration and top speed trade offs; more teeth increase top speed potential while fewer teeth improve initial acceleration. The hard coat helps the gear maintain surface integrity during repeated setup runs and competitive events.

Fitment Details

  • Fits NT1 2015 Specs (330011) chassis variants

Do I need to change the spur gear when fitting this?

The gear is made to match standard NT1 spur geometry so a spur swap is not normally required, but confirm tooth counts and mesh during setup to ensure correct engagement.

Is 7075-T6 better than steel for this position?

7075-T6 aluminium with a hard coat offers a good strength to weight ratio and improved wear resistance for many racers, though steel remains stronger in ultimate toughness. Choice depends on your durability versus weight priorities.

How often should I inspect the gear?

Inspect the gear after a few test runs and then after every intense race day; look for tooth wear and maintain consistent mesh to avoid damage to the spur or other drivetrain parts.
