Durable Spur Gear Built for YZ-4S Chassis

The Yokomo S4-SG84CDA spur gear is aimed at pilots who want a dependable centre diff gear for the YZ-4S. With 84 teeth and a 48 pitch, it promotes even power delivery and repeatable handling on rough tracks.

Compatibility with YZ-4S Line

Specifically matched to YZ-4S models, including B-YZ4SF and B-YZ4SF2-1, the gear offers a straightforward swap and secure seating in the diff. The material choice resists the impacts of off-road running.

Precision Mesh to Extend Service Intervals

A 48-pitch cut helps the spur and pinion run with reduced friction and cleaner tooth contact. That precision means fewer adjustments and a longer service life between rebuilds.
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.

Is this suitable for high-power brushless setups?

The gear is compatible with YZ-4S diffs, but with high-power motors you should monitor tooth wear and ensure bearings and diff internals are in good condition.

How do I check for correct gear mesh?

Use a thin film method to set mesh, look for even tooth contact across the gear face, and verify there is no binding or excessive backlash at idle and under throttle.

Can I run this gear dry or should it be lubricated?

Light, appropriate lubricant on the gear face and diff internals helps reduce wear; avoid heavy greases that can drag the drivetrain and trap debris.
