MUGEN MTX-5 2nd Gear 21T Durable 7075 Aluminum Upgrade - Arrowmax AM-MTX-T2719  [AM-MTX-T2719]

Second stage 21T gear for MTX-5

The Arrowmax AM-MTX-T2719 is a purpose-built 2nd gear for the MUGEN MTX-5, intended as a direct, long-lasting replacement. Machined from 7075 hard aluminum as noted in the model name, the gear is aimed at improving wear resistance and preserving consistent tooth engagement under race and practice loads at RC scale.

Role and tuning: fitted as the second stage inside the MTX-5 gearbox, the 21T 2nd gear helps define the intermediate ratio and therefore influences mid-range acceleration versus top speed when paired with different pinion and spur combinations. Use this gear when tuning drivetrain response or when replacing a worn steel item to lower wear on mating components.

Installation notes: confirm the 21T tooth count and correct centre-to-centre mesh before full assembly, inspect bearings and shafts for any play, and apply a light amount of RC-grade gear grease to the tooth roots only if required. The component is sold as a single gear for direct swap into compatible MTX-5 gearboxes.
