Replacement centre shaft for YZ-4S

Part number S4-010C71A identifies this centre drive shaft for use on YZ-4S platforms, featuring a 71mm dogbone length intended for slipper clutch setups. It provides the direct rear driveline connection between the differential outputs and the drive cups.

The part is a direct-fit service item for the compatible models listed and is intended for replacing worn dogbones or when servicing slipper clutch systems. Correct alignment and secure retention at the drive cups are important for reliable operation.

On installation, confirm the dogbone seats correctly and that there is no excessive axial play. The shaft plays a role in driveline lash and the slipper clutch's spin-up response.

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.

Does this part fit both YZ-4S and B-YZ4SF without modification?

Yes. The part is listed as compatible with both models and is intended to install as a direct replacement on those chassis without modification.

Is the 71mm length critical for correct operation?

The 71mm specification matches the original design length; using that length ensures correct seating in drive cups and maintains intended driveline geometry for slipper setups.

Can I reuse my existing drive cups with this shaft?

Provided the drive cups are not worn or damaged, they can be reused. Inspect contact areas and retention features and replace cups if there is visible wear to ensure secure fitment.

What should I inspect after the first run?

After the initial run, recheck dogbone seating, confirm there is no new play at the ends, and look for unusual wear or noise. Address any issues before continued use.
