Rugged aluminum front shock body for consistent handling

The Yokomo YZ-S4F is a precision machined aluminum front shock body made specifically for the YZ-870C chassis. With a 13mm outer diameter and a 10mm inner diameter, it offers improved durability and repeatable suspension behaviour under heavy use. Tight tolerances help the shocks respond predictably, making it a practical upgrade for pilots tuning front-end feel on paved and mixed surfaces.
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 YZ-S4F fit other Yokomo models?

This part is engineered for the YZ-870C chassis. It may fit other models that use a 13mm outer diameter and 10mm inner diameter shock tube, but you should verify mounting dimensions before fitting.

How should I care for the aluminum shock body?

Keep the shock bodies clean and free of grit, check for burrs after impacts, and lightly lubricate threads and sealing surfaces. Regular inspection will extend service life and preserve performance.

Will this change handling noticeably?

Upgrading to a precision aluminum body like the YZ-S4F promotes more consistent damping response, but overall handling will still depend on shock oil, springs and overall setup.
