YZ-4S centre dogbone overview

This centre drive shaft, sold as S4-010C71A, fits YZ-4S machines and employs a 71mm dogbone length appropriate for slipper clutch setups. It provides the central rear connection that transmits torque from the diff to the drive cups.

As a service part it is offered as an exact-fit option for the compatible models listed, intended to replace worn components during routine maintenance or when servicing a slipper-equipped drivetrain. Correct alignment at the drive cups and diffs ensures secure retention.

Installation notes: confirm that the dogbone seats correctly in each cup and check for any end play. The shaft can influence driveline lash and the way the slipper engages under load.

Remark :

How durable is the S4-010C71A dogbone under regular use?

Durability depends on driving conditions and maintenance. Inspect the dogbone for wear after high-impact runs and replace if you see rounded ends or excessive play.

Should I replace both center dogbones at the same time?

If the paired dogbone shows similar mileage and wear, replacing both helps maintain balanced driveline performance and reduces uneven load on other drivetrain parts.

What signs indicate the dogbone needs replacing?

Look for play at the joint ends, visible wear on contact surfaces, or vibration under throttle. Any of these suggest replacement to avoid further drivetrain damage.

Is the S4-010C71A interchangeable with other lengths?

This part is specified as a 71mm dogbone. Swapping to a different length can affect fitment and driveline geometry, so only use alternate lengths if the chassis is designed to accept them.
