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.

Can I reuse my existing ring gear with this drive gear?

You should pair the S4-503D16A with a compatible ring gear such as the S4-503R16 to ensure correct mesh. Reusing an incompatible ring gear may cause premature wear.

Is this gear suitable for high-power brushless setups?

Yes, the 16T gear is commonly used with modern brushless powerplants, but check overall drivetrain alignment and pinion/ring gear matching to avoid added stress.
