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.

Does the B9-501MA require special pulleys?

The integrated pulley covers most standard setups, but if you run nonstandard belt sizes check compatibility before ordering additional pulleys.

How should I maintain the molded spool?

Keep the pulley area free of debris and inspect for wear after impacts. Light lubrication on moving contacts and regular checks will extend service life.

Will swapping to this spool affect handling?

The spool itself does not change suspension settings, but improved driveline efficiency can give a cleaner throttle response that may affect lap times and handling feel.
