For competitive setup work the 3Racing SAK-A575 provides an exact M5 x 23.8mm dimension intended to preserve driveline geometry on the Sakura Advance 21. Its dimensional consistency helps maintain repeatable alignment during trimming and setup iterations. This component is suitable for methodical tuning workflows where component tolerances matter.
The SAK-A575 is manufactured to match the established M5 x 23.8mm layout for the Sakura Advance 21 driveline. Confirming shaft straightness and secure attachment points during installation will reduce play and support consistent power transfer across runs.
Use this lay shaft when you need a dependable baseline part for testing setup changes, or when replacing worn shafts to restore original driveline geometry. It is intended to stabilise handling inputs and support predictable responses during competitive tuning.
