Mugen Seiki MTX4 2nd Stage Gearbox Housing MTX3-017 by 3Racing  [MTX3-017]

Second-stage gearbox housing for MTX4

This 2nd gear housing is a replacement component for the Mugen Seiki MTX4 chassis, listed under model MTX3-017. It serves as the casing for the second-stage spur and associated bearings within the MTX4 transmission and is intended for maintenance jobs, part swaps, or a full gearbox rebuild on that platform.

Fitment is specific to the MTX4 gearbox arrangement so verify your chassis before ordering. When installing the replacement, make sure to restore gear mesh and bearing preload to factory-like settings to avoid premature wear. Inspect the spur gear and bearings while the case is open and replace any worn items at the same time.

Ideal for restoring correct second-stage alignment and clearances on MTX4 gearboxes during servicing or after impact damage.
