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.

How many pieces arrive in the SD-643A package?

You get one ring gear and one drive gear plus three pan-head tapping screws (2x5mm) to mount the assembly in compatible Drift Package gearboxes.

Can I fit this without modifying the chassis?

This set is intended as a direct replacement for the original Drift Package gears on compatible models. Check tooth mesh and gearbox clearances, but no major chassis mods are normally required.

What should I check after installation?

After fitting, rotate the drivetrain by hand to confirm smooth engagement, verify correct mesh and screw torque, and test under low power before full use.
