Refine Your Sakura D4 Drivetrain

The 3Racing SAK-D4841B pinion gear is tailored for the Sakura D4 chassis, employing a 48 pitch and 40 tooth arrangement to improve gear engagement and produce steadier power transfer during runs.

48 Pitch Accuracy for Cleaner Engagement

The 48 pitch tooth form promotes even contact with matching spur gears, helping to limit uneven wear. The 40 tooth option provides a sensible route to increase top speed in a tuned setup.

Compatibility Notes and Fitment

Made for Sakura D4 models, this pinion fits standard motor pinion mounts and is a practical choice when upgrading gearing or replacing a worn pinion.

Will this work with upgraded motors?

It is compatible provided the upgraded motor uses a standard pinion mount and the shaft size matches. Always verify mechanical compatibility before installation.

Does tooth count change gearing range?

Yes, increasing pinion teeth raises the gear ratio which tends to increase top speed but reduces initial acceleration. 40T is commonly used when more top end is desired.

How to check for wear?

Inspect teeth for rounding or chips and listen for irregular noises. Replace the pinion if wear affects mesh or creates excessive backlash.
