Rear Shock Cylinder for Yokomo YZ-870C

The Yokomo YZ-S4R rear shock body is a direct fit part for the YZ-870C chassis and is recommended when servicing or upgrading your rear dampers. It features an inner diameter of 10mm and an outer diameter of 13mm, crafted from aluminium to help maintain consistent oil seals and resist wear during aggressive club or track use.
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 the Yokomo YZ-S4R work with YZ-870C stock springs?

Yes, the YZ-S4R accepts the standard rear springs designed for the YZ-870C; spring rate choices remain unchanged when swapping the body.

What shock oil viscosity is suitable for this aluminium body?

Use the same shock oil viscosity you run now on the YZ-870C; aluminium bodies do not change recommended oil but can improve temperature stability on long runs.

Any tips for maintaining the YZ-S4R shock body?

Regularly inspect O rings and piston for wear, clean aluminium surfaces with a mild solvent, and replace seals when you notice oil seepage to keep damping consistent.
