Reliable Main Shaft Upgrade for Sakura M4

The 3Racing Sakura M4 Main Shaft SAK-M4S37 is a precision component aimed at reducing drivetrain play and improving longevity. It helps maintain consistent torque delivery under race and practice conditions.

Performance and Durability

Upgrading to this main shaft reduces vibration and uneven wear in the driveline, offering steadier response and fewer service intervals compared with worn stock parts.

Compatibility and Swap Guide

Engineered to fit the Sakura M4 layout, the SAK-M4S37 installs using the same mounting points as the original shaft and requires no custom modifications, making it a practical replacement part.

Will this fit without trimming the chassis?

Yes, it is designed for direct fit into standard Sakura M4 chassis layouts and should not require trimming unless prior modifications have been made.

Is this suitable for competitive club racing?

Its tighter tolerances and improved durability make it a sound upgrade for club level competition where consistent drivetrain behaviour matters.

How often should I inspect the shaft?

Check gear mesh and bearing condition after any heavy session and perform routine inspections every few runs to ensure no unusual wear develops.
