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 the optional centre differential on the YZ-4S?

Yes, the S4-503DCA is compatible with the optional centre differential as well as the front and rear gear differentials of the YZ-4S.

How many units are supplied in one pack?

The item is supplied as a pair, so you receive two drive cups per pack.

Maintenance tips to prevent premature wear?

Keep the spline area free of grit, apply appropriate grease, and inspect for wear during routine differential servicing to extend component life.

Can I swap these into other brand diffs?

They are specified for Yokomo YZ-4S differentials; confirm spline count and dimensions before fitting to non-Yokomo gearsets.

Are there special tools needed for fitting?

Typical small hand tools are sufficient for assembly, though using a vice or soft jaws can help seat the cup without damaging splines.
