Dial In Gear Ratio with the 14T Clutch Bell

The Tamiya 84039 - TRF801XT Clutch Bell (14T) is aimed at pilots wanting a more race-oriented gear setup. It changes the gear ratio to 1:15.36 compared with the 13T unit at 1:16.54, giving a noticeably firmer final drive. Racers can use this bell to sharpen throttle response and extract more speed on long straights.

Why Fit a 14T Bell for Racing

Choosing the 14T bell lets you tailor the car's power delivery to suit circuit conditions, offering stronger mid to high range performance. It is a practical choice for competitors refining gear choices without altering the core drivetrain.

Drivers who prioritise quicker acceleration and stronger top-end on flowing tracks will notice the biggest gains from the 14T ratio change.
Most standard clutch components for the TRF801XT will work with the 14T bell, but inspect spline fit and clearance and make minor adjustments to maintain proper mesh and free play.
After fitting, check clutch engagement, pinion mesh, and perform a low-speed test run to confirm there are no binding issues and the car launches cleanly.
