MUGEN MTX-5 21T 2nd Gear Precision Upgrade - Arrowmax AM-MTX-T2719  [AM-MTX-T2719]

MTX-5 21-tooth second gear

The Arrowmax AM-MTX-T2719 is manufactured as a 2nd gear replacement for the MUGEN MTX-5 platform, intended for enthusiasts seeking a robust direct-fit component. Made from 7075 hard aluminum, it targets improved wear resistance and reliable tooth engagement under regular track and practice stresses.

Role and tuning: occupying the second gear position in the MTX-5 transmission, the 21T gear contributes to the car's intermediate ratio and plays a role in mid-range performance versus top speed depending on pinion and spur pairings. Choose this gear for tuning sessions focused on drivetrain response or when eliminating wear from older steel parts.

Installation notes: double-check the 21T tooth count and correct centre spacing prior to full assembly, inspect bearing seats and shaft for any looseness, and apply minimal RC gear grease to the roots of the teeth where appropriate. The item is sold as a single gear unit compatible with MTX-5 gearboxes.
