Precision Pinion Upgrade for Sakura D4

The 3Racing SAK-D4841B pinion is made for the Sakura D4 chassis with a 48 pitch and 40 tooth layout, designed to improve drivetrain accuracy and provide a smoother transfer of motor power for club and local track sessions.

48 Pitch Mesh for Consistent Performance

The 48P profile matches common spur gears to reduce backlash and uneven wear. The 40T tooth count offers a useful tuning step so you can adjust the balance between top speed and acceleration without major changes to gear ratio options.

Direct Fit and Straightforward Installation

Purpose built for the Sakura D4 series, this pinion fits standard motor shafts used in the kit and installs quickly. It is suitable for racers and hobbyists performing upgrades or routine maintenance.

Will this pinion fit other Sakura variants?

This pinion is specified for the Sakura D4 series. It may fit other models that use a 48 pitch motor pinion but you should check shaft diameter and mounting method before fitting.

How does 40 teeth change gearing feel?

A 40T pinion raises the overall ratio compared with smaller pinions, tending to increase top speed while reducing initial acceleration; it is a common choice for track tuning where higher top speed is needed.

Any setup tips after fitting?

Check gear mesh with a thin sheet of paper, secure any grub screws, and inspect mesh after a short run. Light gear lubricant on the spur can help reduce noise and wear.
