Upgrade Your Sakura M4 Drivetrain

The 3Racing Sakura M4 Main Shaft SAK-M4S37 is a precision part intended to strengthen the drivetrain and keep power transfer consistent across varied running conditions. Its accurate production reduces slop and improves responsiveness.

Performance Advantages

Small improvements in drivetrain components make noticeable differences on track. This main shaft raises torsional rigidity and lessens drivetrain play so acceleration and braking inputs feel more direct.

Simple Replacement and Compatibility

Built for the Sakura M4 layout, the SAK-M4S37 drops into the factory locations and does not need additional modifications. This makes it a convenient upgrade when replacing a worn component or preparing a tuned setup.

Will this fit a modified Sakura M4?

It fits standard Sakura M4 configurations. If the chassis has nonstandard mods affecting the drivetrain tunnel, check clearances before installation.

Is it suitable for daily hobby use?

Yes, the SAK-M4S37 is durable enough for regular club runs and practice sessions while still offering performance benefits for occasional racing.

Any maintenance tips after fitting?

Inspect gear mesh and bearing play after installation, and use a light lubricant on moving interfaces to prevent corrosion and wear.
