16T Metal First Gear for MTX-4

This aluminium hardened first gear is designed for the Mugen MTX-4 chassis and replaces the OEM first gear with a 16-tooth metal unit. It is intended to lengthen drivetrain life and provide steadier engagement under load while remaining a model-only component for MTX-4 platforms.

Fitting is a gearbox-level job: open the case, swap the first gear for the new 16T, assess adjacent bearings and pinion/spur alignment, then set mesh and check rotation before closing the gearbox. Re-inspect the mesh after initial runs to confirm stable engagement and check for early wear.

As a tuning aid, the metal first gear gives predictable mesh behaviour useful when fine-tuning gear preload or troubleshooting drivetrain noise. It is a practical hop-up for competitive builders who keep MTX-4 kits in top condition.

Which models will accept this gear?

It is made to fit the Mugen MTX-4 first gear location as a like-for-like replacement; confirm fit on your gearbox before assembly.

Is any special bedding-in required?

No special break-in is mandated, but short trial runs with subsequent mesh checks help ensure the gear seats evenly and wears predictably.

Should I replace bearings at the same time?

Inspect bearing play during the gearbox service; replace any worn bearings to protect the new metal gear and preserve mesh alignment.
