Engineered Spur Gear for YZ-4S Racing

RC builders looking for dependable drivetrain parts will find the Yokomo S4-SG84CDA a solid match for the YZ-4S center differential. Its 84-tooth count and 48 pitch are tuned to deliver steady torque transfer during competitive runs.

Designed to Match YZ-4S Variants

Compatible with YZ-4S family cars including B-YZ4SF and B-YZ4SF2-1, this spur gear ensures straightforward installation and consistent engagement. The construction is intended to take regular on-track stresses in stride.

Fine 48P Mesh for Lower Friction

The 48-pitch geometry allows closer tooth contact with the pinion, which lowers vibration and reduces wear. That leads to improved drivetrain efficiency and fewer service intervals.
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.

Will this fit older YZ-4S gearboxes?

It is intended for YZ-4S center differentials and most YZ-4S versions, but check that the diff housing and mounting points match your older chassis before fitting.

Does the 48-pitch mean quieter running?

Yes, a finer 48-pitch mesh typically reduces gear noise and vibration compared with coarser pitches, assuming the mesh and bearings are set correctly.

Are there recommended pinion sizes to use?

Pinion size depends on your motor and track; start with a conservative tooth count to protect the 48P mesh, then adjust for speed while monitoring gear temperature and wear.
