Remark :
Due to limited stock availability, please notice that some Yokomo 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 dogbone work in other Yokomo cars?

This part is engineered for the YZ-4S and the B-YZ4SF chassis. It may not fit other models without checking shaft lengths and joint geometry first.

How can I tell when the dogbone needs replacing?

Look for excess play at the joints, unusual clunking under acceleration, or visible bending. Regular visual checks after runs will catch wear early.

Any tips for installation and upkeep?

Keep the dogbone free of grit and inspect the cups and bearings when changing the shaft. Fit with the correct hardware and torque to factory recommendations to avoid premature wear.
