Smoother drivetrain for the Sakura M4

The 3Racing SAK-M4S30 Gear Differential is built to refine how your Sakura M4 transfers power through the drivetrain. The 38-tooth arrangement focuses on steady torque balance and tighter handling response, making it a practical upgrade for club racers and weekend track days.

Benefits of the 38T gear layout

The 38T configuration helps reduce abrupt torque spikes and promotes more linear power delivery to the wheels. That results in improved traction on exit and more predictable behaviour during fast direction changes.

Fitment and simple installation

Made to match the Sakura M4 series, the SAK-M4S30 fits into the stock layout without complex modification. Its precision design aims for a straightforward swap so you can return to running laps quickly.

Can I use the SAK-M4S30 in older Sakura M4 variants?

The SAK-M4S30 is optimised for Sakura M4 layouts. Some earlier or heavily modified variants may require checking gearbox spacing and axle fitment before installation.

What diff oil should I run with a 38T gear differential?

Viscosity choice depends on driving style and track conditions. Lightweight oils give quicker transient response; heavier oils increase traction and stability. Test a few weights to find the best balance for your setup.

How difficult is the swap from the standard differential?

If you are familiar with basic gearbox work, the swap is straightforward. Keep gear mesh and bearing preload correct and check for smooth rotation before reinstalling the gearbox covers.
