XRAY NT1 23T Lightweight Pinion 2nd Gear - Arrowmax AM-NT1-338523  [AM-NT1-338523]

Second Gear 23T - NT1 Fitment

This 23T 2nd gear pinion is an upgrade part for the XRAY NT1 chassis, supplied as Arrowmax AM-NT1-338523. Fabricated from 7075-T6 aluminium and treated with a hard coating, the pinion aims to maintain stable mesh with NT1 spur gears while minimising rotating mass for crisper driveline feel.

Setup and tuning notes: fit this pinion to alter final ratio or to pair with a specific motor pinion during setup. It connects into the NT1 gearbox train, so check mesh, endplay and run-in behaviour during the initial install before pushing for race power.

Practical fitting tips: use the NT1s standard clutch or pinion mounting method, tighten by hand to locate the gear then relax slightly to set correct engagement, and confirm the hard-coated surface has adequate clearance from the spur. The same Arrowmax family includes other tooth counts to let you dial acceleration versus top speed without overstressing the NT1 drivetrain.
