Description
FAQ

Main shaft for YZ-4

This is an optional RC-scale main shaft for the YZ-4 platform supplied under Yokomo Z4-644H. The part is made from aluminum with a hard anodized surface finish to resist wear while keeping mass lower than standard steel shafts, and it is intended for drivetrain use on YZ-4 models.

Functionally, the shaft serves as a direct drivetrain component that can alter rotating mass in the gearbox assembly. Reducing inertia on this axis can yield quicker throttle response in electric RC buggies; changes are subtle and intended for fine tuning, not fundamental driveline redesign.

Installation notes: this part is an optional replacement for the stock main shaft on compatible YZ-4 builds. Fitment requires basic gearbox disassembly to access the existing shaft and bearings, verify bearing alignment and clearances after installation, and confirm secure seating before running the model. No additional tools or modifications are specified with the source information.

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.

Is this shaft a direct replacement for the YZ-4 stock shaft?

It is offered as an optional replacement for YZ-4 line items, check fit and bearing clearances during installation to confirm compatibility.

What performance change should I expect after fitting this shaft?

Expect modest reduction in rotating mass that can improve throttle response and sensitivity during fine tuning, results depend on the whole drivetrain setup.
