Racing focused centre pulley for consistent drive

The 3Racing Sakura Ultimate Center Pulley 20T Set is specified for the stock 20T2014 chassis and uses a 2.0 gear ratio to stabilise torque flow through the centre of the car. This component is intended for drivers who want predictable drivetrain behaviour during setup changes and race conditions.

Technical highlights for competitive tuning

  • Compatibility: Direct fit for Sakura Ultimate stock 20T2014 mounting points to minimise modification time.
  • Gear Ratio: The 2.0 ratio provides a measured step in final drive suitable for tuning traction balance.
  • Construction: Manufactured to maintain consistent tooth engagement under race loads.
  • Setup Impact: A stable centre ratio that assists in retaining chassis balance when tweaking front and rear differentials.

How does the 2.0 centre ratio interact with differential settings

Using a 2.0 centre pulley changes the torque split behaviour; expect altered traction balance that may require small differential oil or preload changes to restore preferred handling.

Are there specific gearbox checks for race use

Ensure accurate gear mesh, check shaft endplay and verify bearing condition before each event to prevent power losses and maintain repeatable lap times.

What tuning gains are typical with this pulley

Expect improved throttle modulation and reduced drivetrain shock during acceleration, which helps drivers fine tune corner exit behaviour without radical changes to other components.

Is this part recommended for club and regional competition

Yes, it suits club and regional competition where consistent drivetrain response is preferred; always confirm class rules regarding drivetrain modifications.
