Racing grade drivetrain refinement

The 3Racing SAK-M4S30 Gear Differential is specified for Sakura M4 chassis users who need a predictable diff feel for tuning. The 38-tooth gearset delivers a stable torque transfer profile useful when dialing in handling balance.

Tuning advantages for competitive setups

On-track, the 38T arrangement supports consistent load distribution across the drivetrain, aiding traction control and allowing finer adjustment of differential oil and suspension to match lap conditions.

Installation and setup considerations

Designed to fit Sakura M4 gearcases, the SAK-M4S30 should be installed with careful attention to gear mesh and bearing preload. Small setup changes to diff oil weight and suspension settings can unlock better corner entry and exit behaviour.

How does the 38T tooth count affect tuning options?

A 38T gear changes the mechanical response compared with other tooth counts, offering a smoother torque ramp that complements fine-tuning of diff oils and suspension settings for consistent lap times.

What setup checks are critical after fitting?

Verify gear mesh, bearing seating and rotation smoothness. Then evaluate diff oil weight and perform short test runs to assess understeer or oversteer tendencies for incremental tuning.

Is this differential suited to sprint and oval race formats?

Yes, the predictable power delivery of the 38T setup helps drivers maintain consistent lines and reduce lap-to-lap variability across sprint and short oval formats.
