Upgrade your Sakura Ultimate with the 3Racing 20T adaptor

The 3Racing Sakura Ultimate 20T Gear Adaptor, model SAK-U121/PK, is engineered to refine drivetrain response on Sakura Ultimate cars. This adaptor is made to fit the Sakura Ultimate series for reliable engagement and simple installation. Its strong build gives long service life, making it a practical choice for racers and club drivers who want consistent gear performance.

Benefits of the 20-tooth configuration

The 20T layout provides predictable gear ratio behaviour and helps the transmission run with less vibration, aiding smoother power transfer and improved handling feel. Compatibility with Sakura Ultimate parts keeps swaps quick and maintenance straightforward for regular track use.

How difficult is installation for the SAK-U121/PK?

Installation is typically simple with basic RC tools; it replaces the original adaptor on Sakura Ultimate transmissions and uses the same mounting points. Check gear mesh and secure fasteners after fitting.

Will this change my gearing noticeably on the track?

The 20T profile alters the final drive behaviour slightly, delivering smoother power delivery rather than a radical ratio change. It is best used as part of a tuning approach with pinion and spur adjustments.

Any maintenance tips for longevity?

Keep the area free of grit, inspect teeth for wear, and confirm gear mesh after running. Periodic checks of fasteners will prevent loosening under load.
