Mugen MTX-5 20T Hardened 7075 Aluminium 2nd Gear - Arrowmax AM-MTX-T2718  [AM-MTX-T2718]

20T Second Gear for MTX-5 Gearbox

Arrowmax AM-MTX-T2718 is a hardened 20-tooth second gear intended as an aftermarket 7075 aluminium replacement for Mugen MTX-5 drivetrains. The gear transmits torque between the motor pinion and spur while resisting wear during intensive running.

When installing, check gear mesh against the spur and pinion, ensure shafts and bearings are free from play, and confirm axial alignment before power testing. The 7075 aluminium grade prioritises dimensional stability and reduced wear under load.

Make this gear part of your drivetrain setup checklist: set correct backlash, ensure bearings share radial loads, and inspect teeth after initial runs for uneven contact. This component is designed for RC drivetrain use on Mugen MTX-5 compatible cars.
