MUGEN MTX-5 Mid Ratio 2nd Gear 21T Aftermarket Part - Arrowmax AM-MTX-T2719  [AM-MTX-T2719]

21T second gear built for MTX-5 use

The Arrowmax AM-MTX-T2719 serves as a dedicated 2nd gear replacement for MUGEN MTX-5 owners who want a reliable swap-in option. Constructed from 7075 hard aluminum, the gear emphasises durable tooth faces and stable meshing under typical RC running conditions.

Role and tuning: positioned as the gearbox second stage, the 21T alters the car's intermediate gearing and will affect how the model pulls through the mid-range versus its top-end when combined with different pinion and spur choices. Fit this gear when evaluating drivetrain responsiveness or replacing a worn alloy item to protect associated gearsets.

Installation notes: confirm the 21-tooth specification and set centre-to-centre clearance before final tightening, check bearing fit and shaft condition, and use a small smear of appropriate gear grease at the tooth roots only if necessary. The item is supplied as one gear for direct installation in compatible MTX-5 gearboxes.
