Precision Spur Gear for YZ-4S Builds

For hobbyists who demand accurate drivetrain parts, the Yokomo S4-SG84CDA spur gear is built to fit the YZ-4S center differential. This 84-tooth, 48-pitch component promotes steady power delivery and helps keep your setup running consistently on the circuit.

Fit and Compatibility with YZ-4S Chassis

Made to match YZ-4S series specifications, including models such as B-YZ4SF and B-YZ4SF2-1, the gear installs cleanly and maintains correct clearances. Its robust construction stands up to regular racing use.

48-Pitch Mesh for Reduced Wear

The 48-pitch profile produces a fine, accurate mesh with compatible pinions, which lowers friction and slows wear. That precision leads to better drivetrain efficiency and less routine maintenance between events.
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 this spur gear be used in modified YZ-4S builds?

Yes. The gear is designed for YZ-4S center diffs and fits common YZ-4S variants, but double-check pinion spacing and mount points if your chassis has non-stock parts.

How should I set mesh with a 48-pitch pinion?

Start with a thin shim or paper method to establish a snug contact pattern, then fine-tune with small adjustments until the teeth sit evenly across the face of the gear.

What maintenance keeps this gear lasting longer?

Inspect for chipped teeth after heavy runs, keep bearings and diff clean to avoid side loads, and ensure correct lubrication to reduce wear on the 48-pitch teeth.
