Optimise V ONE R4 Gearing with Kyosho VZ413-55B

If you need more control over gearing on a V ONE R4, the Kyosho VZ413-55B 55T spur gear is a direct-fit tuning option. Designed around the V ONE series architecture, it supports accurate ratio selection to refine acceleration characteristics and top speed balance. Its tooth count enables finer adjustments during setup and is useful both for routine upkeep and targeted performance changes.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this spur work on other manufacturer's cars?

This part is made for Kyosho V ONE R4 dimensions. Cross-brand compatibility is unlikely without modification.

How should I adjust gear mesh with a new spur?

Start with a small shim adjustment, check for even tooth contact, and rotate the drivetrain to confirm smooth engagement before finalising the mesh.

What signs show the spur needs replacing?

Look for rounded or chipped teeth, unusual noise, or slipping under load; these indicate it is time to replace the spur.

Will changing to 55T affect corner exit speed?

Adjusting the spur alters overall gearing which can change acceleration out of corners; testing on your usual track will reveal the practical effect.

Any pre-run checks after installing this spur?

Verify mesh, ensure no binding in the drivetrain, and run a brief low-speed test to confirm normal operation before full-power runs.
