Engineers and racers who set up the Sakura Advance 2K18 EVO will welcome the 3Racing SAK-U421/V3 centre pulley set as a concise tuning option. The 20T pulleys are intended to harmonise rotational load through the centre drive, supporting predictable torque transfer under race conditions.
When integrating the 3Racing centre pulleys, verify mesh and fastener torque, then test with controlled runs to confirm desired drivetrain behaviour. Small adjustments to differential preload or gear engagement can be used to tune the overall response for specific track conditions.
