Balanced drivetrain upgrade for consistent lap times

Built for the Sakura Advance 20M chassis, the 3Racing SAK-A521/V2 gear differential set uses a 38T arrangement to even out power delivery and reduce sudden breakaway. This Version 2 set aims to give smoother mid-corner drive and repeatable feel lap after lap, suited to hobbyists refining setup for club meetings or practice sessions.

Specifications

Compatibility: Sakura Advance 20M
Gear Tooth Count: 38T
Version: 2

A pragmatic upgrade for the Sakura Advance 20M, this differential set helps stabilise handling and maintain reliable performance during regular use.

Is additional setup required after swapping differentials?

After installation, it is recommended to verify gear mesh, differential preload and apply a suitable diff oil to match your driving style.

Will this change gear ratio or top speed?

The 38T tooth count relates to internal differential gearing and affects torque feel rather than the external gear ratio, so top speed is largely unchanged.

Can I use this for both practice and race days?

Yes, the SAK-A521/V2 performs reliably in everyday running and holds up under competitive conditions with proper maintenance.
