Technical overview of the 3Racing gear differential

The 3Racing SAK-A521/V2 gear differential set is engineered for the Sakura Advance 20M chassis and utilises a 38T gear arrangement to refine torque transfer characteristics. Version 2 focuses on reliable tooth engagement and repeatable behaviour under variable load, making it suitable for racers aiming to tune diff behaviour precisely.

Specifications

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

For setup-driven drivers, this differential provides a consistent baseline that integrates with common tuning changes to achieve predictable lap to lap performance.

What impact does 38T have on diff behaviour compared to other tooth counts?

The 38T count alters internal engagement geometry which affects slip onset and torque mapping; this is useful when tuning for steadier mid-corner drive without changing external gearing.

Any recommended setup notes for competitive use?

Verify bevel mesh accuracy, select diff oil viscosity to match track grip and check preload to obtain the desired lock versus slip characteristic for your driving style.

How does Version 2 differ in serviceability?

Version 2 maintains easy access for routine inspection and rebuilds while offering refined internal engagement to reduce premature wear when correctly set up.
