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.

What exactly comes in the B9-503GPA kit?

The kit contains the molded bevel gears along with the cross pins required for installation into the BD9 gear differential.

Will these gears fit my older Yokomo chassis?

They are compatible with multiple Yokomo models listed above; check your chassis manual to confirm differential compatibility before fitting.

Any tips for installing the bevel gears correctly?

Make sure gear faces are clean, set correct mesh with a shim or finger test, and secure cross pins fully. Light grease on bearing surfaces helps break-in.
