MTX-4 23T Second Gear Hardern Aluminium MTX4-0823 by 3Racing  [MTX4-0823]

23-Tooth Hardern Aluminium Second Gear for MTX-4

This aluminium second gear is offered as a direct replacement for the Mugen MTX-4 buggy drivetrain. Machined from Hardern aluminium, the 23-tooth component is the gearbox intermediate gear and is intended for scale rebuilds and compatible transmissions with the same gear geometry.

Fitment details: manufactured to engage MTX-4 gearbox internals, the part works with the vehicle's spur and pinion configuration to determine final drive ratios. It is not a one-size-fits-all gear and should only be used where geometry matches.

Installation guidance: when replacing the second gear inspect bearings and shafts for wear, set correct mesh and backlash and verify pinion alignment after fitting. Retain original mounting orientation and torque fasteners to recommended values to avoid housing or gear distortion.

Tuning application: installing this 23T second gear alters overall ratio in modest increments and can be combined with different spur or pinion sizes to balance acceleration vs top speed. Being aluminium, expect variations in wear and heat dissipation compared with steel or nylon gears, so monitor mesh and run controlled tests.
