Technical Overview of the 3Racing SAK-40H Swing Shaft

The 3Racing SAK-40H 42mm swing shaft is engineered for Sakura Zero and Zero S chassis to improve drivetrain stiffness and reduce deflection under competitive loads. Its heavy duty construction is intended to maintain consistent torque transfer and support repeatable setup changes for serious racers.

Technical Highlights

  • Compatibility: Engineered to match Sakura Zero and Zero S drivetrain geometry.
  • Durability: Specified for sustained racing cycles to minimise premature fatigue.
  • Performance: Reduces drivetrain compliance for more predictable power delivery in high load situations.
  • Precision Fit: Manufactured to maintain tight alignment with standard transmission components.

What chassis checks should be done before fitting?

Inspect spline condition, bearing bore tolerances and mating hardware. Replace any worn bearings and verify axial alignment to prevent binding.

How does shaft stiffness affect setup tuning?

Increased shaft stiffness reduces drivetrain losses and can alter mid corner traction feel; consider small incremental setup adjustments to differential and suspension to rebalance handling.

Recommended inspection intervals for race use?

For regular competitors inspect splines and bearing seats every few race meetings, and replace any components showing play to retain optimal performance.
