Center drive shaft tailored for YZ-4S

Designed for YZ-4S models, this center drive shaft is supplied under part number S4-010C71A and uses a 71mm dogbone length suited to slipper clutch configurations. It serves as the rear central link that transfers torque through the drive cups and differential outputs.

Offered as an exact-fit service replacement for the listed compatible chassis, the part replaces worn dogbones and is suitable when maintaining or converting a slipper-equipped driveline. Proper fitment relies on correct alignment and secure retention at the drive cup ends.

When fitting the shaft, confirm full seating in each drive cup and check for axial play at both ends; the shaft affects driveline lash and spin-up behavior in slipper arrangements.

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.

How should I seat the 71mm dogbone during installation?

Ensure the dogbone ends fully locate in the drive cups and that the retaining pins or screws are tightened to the recommended torque. Proper seating prevents bind and uneven wear.

What checks do I make after fitting this shaft?

After installation, rotate the drivetrain by hand to confirm smooth operation, inspect for axial play at both ends, and run a short low-speed test to verify engagement before full use.

Is any special lubrication required for the drive cups?

Light grease on the drive cup contact areas can reduce wear and noise, but avoid excess that could attract debris. Follow general driveline maintenance practices for best results.

Will this part change my chassis geometry?

No. This 71mm dogbone is a direct replacement and is intended to preserve the original geometry while restoring driveline reliability.
