Tuned Performance: Yokomo S4-S1SA Front Shocks

Focused on improving control, the Yokomo S4-S1SA Front Shock Set employs a 3.0mm shaft to lower friction and refine rebound behavior. It fits the YZ-4SF2 and can be used as an upgrade for YZ-2DTM3/CAL3 to sharpen handling and response.

How the Design Affects Setup

These shocks are built for several Yokomo chassis such as the YZ-4SF2 and YZ-2DTM3/CAL3, offering clearer feedback and more predictable travel compared with standard units, which helps when dialing in suspension settings.

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.

Which oil weight pairs well with the 3.0mm shaft for firmer handling?

For a firmer feel, use a higher viscosity shock oil and reduce free play in the shock assembly; this increases resistance and helps the 3.0mm shaft control large impacts. Adjust gradually while testing.

How does the larger shaft influence rebound tuning?

A thicker shaft smooths shaft movement and reduces stiction, allowing more consistent rebound. That stability makes fine-tuning rebound settings simpler and more repeatable.
