Mugen MTX-4 16 Tooth Metal First Gear - MTX4-0816 by 3Racing  [MTX4-0816]

Metal 1st Gear, 16 Teeth, for MTX-4

This hardened aluminium 16T first gear is intended as a direct replacement for the Mugen MTX-4 stock part. It helps maintain consistent engagement and extend the drivetrain service interval compared with older plastic gears, and is supplied for model car use on MTX-4 platforms.

Installation is performed at the gearbox level: remove the case, fit the 16T gear, inspect nearby bearings along with spur and pinion alignment, then set mesh and verify smooth rotation before reassembly. Repeat checks after initial runs to confirm correct mesh seating and early wear characteristics.

For racers and hobbyists tuning their MTX-4, this metal gear provides repeatable engagement when adjusting mesh, preload, or diagnosing noise in the drive train. It is a straightforward upgrade for those wanting a tougher first gear option.
