Mugen MTX-5 2nd Gear 20T 7075 Aluminum Upgrade - AM-MTX-T2718 by Arrowmax  [AM-MTX-T2718]

Second Stage 20T for MTX-5 Drivetrain

This Arrowmax AM-MTX-T2718 second gear is a hardened 20-tooth component made for Mugen MTX-5 chassis drivetrains, intended as a direct replacement where a 7075 aluminum gear is preferred. It functions as the intermediate gear transferring torque from the motor pinion to the spur while resisting wear during extended track sessions.

When installing, check gear mesh with the spur and motor pinion, make sure bearings and shafts have no play, and confirm axial alignment before running at full power. The 7075 hard alloy delivers dimensional stability and wear resistance under load, helping maintain consistent gear engagement after setup.

Include this gear in your drivetrain tuning routine: set correct backlash, share loads across bearings, and inspect tooth faces after the first runs for any uneven wear. This part is intended for RC drivetrain use on Mugen MTX-5 compatible models.
