Fine-Tune Final Drive with the 14T Clutch Bell

The Tamiya 84039 - TRF801XT Clutch Bell (14T) is built for hobbyists who want precise control over gear ratios. This high gear type clutch bell gives a refined final ratio of 1:15.36 versus the 13T version's 1:16.54. Swapping to the 14T unit helps create a more aggressive gear setup that can improve acceleration and top-end speed for track-focused builds.

Track Advantages of a 14T Bell

Moving to a 14T clutch bell changes how the car responds under throttle, producing crisper acceleration and better high-speed progress. It is a tactical upgrade for drivers tuning for specific tracks or seeking a more immediate throttle feel without major drivetrain changes.
