3Racing SAK-D412 belt tension support for Sakura D4 chassis

The 3Racing Sakura D4 Belt Tension Bearing SAK-D412 is a targeted component to maintain belt preload in the Sakura D4 belt run. Properly positioned, the bearing reduces transient belt movement that can complicate high speed drivetrain behaviour, allowing more consistent torque transfer and aiding precise setup adjustments. It integrates with the stock belt path to preserve chassis geometry while offering a straightforward option for tuning refinement.

What setup checks should I do after fitting the SAK-D412?

After installation confirm belt alignment and tension across the full range of suspension travel. Run the chassis slowly and verify the bearing rotates freely without contact before full speed testing.

Does the bearing change tuning approach for competitive use?

The SAK-D412 aims to stabilise belt behaviour so setup changes to suspension and differential feel are easier to evaluate. It reduces drivetrain variables that can mask handling changes during tuning sessions.
