XRAY NT1 16T First Pinion 7075-T6 Hard-Coated - Arrowmax AM-NT1-338516  [AM-NT1-338516]

16T First Pinion for XRAY NT1 Applications

This 16-tooth first gear pinion is made for XRAY NT1 use and is sold as Arrowmax part AM-NT1-338516. Machined from 7075-T6 aluminium with a hard-coated surface, it is a light replacement pinion that keeps accurate engagement with the spur gear while enabling quick gearing swaps on the pit table.

Fitment is direct on NT1 clutch and pinion assemblies where a 16T option is required. Choose this pinion when you want a modest change to final drive to tweak launch or mid-corner behaviour; combining different pinion tooth counts with the vehicle spur alters overall ratio without changing gearbox geometry.

Installation tips: check pinion-to-spur mesh before final assembly, tighten the set-screw to the motor shaft without cross-threading, and inspect for burrs or sharp edges after mounting. The hard-coated 7075 core emphasises wear resistance and a stable tooth profile rather than affecting motor or ESC characteristics.

The Arrowmax NT1 pinion family includes 16T, 17T, 18T, 19T, 20T, 21T, 22T and 23T so drivers can pick fine steps for ratio tuning while keeping the same material and finish across sizes.
