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 use this on both carpet and asphalt tracks?

Yes, the part is suitable for different on-road surfaces; tune diff oil and gear mesh to suit the grip and track surface for best results.

Will this work with aftermarket bearings and gears?

It accepts common upgrades like hardened gears and higher-grade bearings, which can further improve drivetrain smoothness and durability.

How do I check pulley alignment after fitting?

Spin the drivetrain by hand and inspect for wobble or uneven mesh; adjust mounting points and shims until engagement feels even across the pulley.
