Refine Your Gear Setup with the 14T Clutch Bell

The Tamiya 84039 - TRF801XT Clutch Bell (14T) is crafted for enthusiasts wanting more control over final drive. The 14T configuration sets the ratio to 1:15.36, compared with the 13T version at 1:16.54, enabling a more assertive gearing profile. That shift can help achieve stronger midrange pull and higher terminal speed on fast sections.

When to Use the 14T Option

Opt for the 14T bell when you need a livelier throttle and extra pace on straights. It is a targeted upgrade for competitors tailoring their car to specific circuits while retaining the stock drivetrain layout.

On tracks with long straights the tighter ratio can yield better top speed and quicker midrange acceleration, which may contribute to faster lap times when matched with suitable gearing and power.
Regular checks of gear mesh, clutch engagement, and bearing condition are advisable after installation to ensure the new ratio does not introduce undue wear or overheating.
Yes, swapping back to the 13T unit restores the original 1:16.54 ratio and a milder power delivery; keep both bells handy to test which suits a given track or driving style.
