This 23-tooth 2nd gear pinion is an aftermarket replacement intended for the XRAY NT1 platform and is supplied by Arrowmax as AM-NT1-338523. It is CNC machined from 7075-T6 aluminium and finished with a hard coating to keep weight low while promoting consistent mesh with NT1 spur gears for predictable driveline behaviour.
When to use this gear: install it to change the final drive ratio or to match different motor pinions during setup. The unit interfaces directly with the NT1 gearbox train; always check gear mesh and endplay during fitting and confirm that run-in friction is stable before applying full power.
Fitting advice: retain the NT1 clutch or pinion mounting method, hand-tighten initially to seat the part then back off slightly to achieve correct engagement, and verify the hard-coated face clears the spur gear without binding. Arrowmax offers the same design in multiple tooth counts so you can trade acceleration against top speed while staying within NT1 drivetrain limits.
