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.

Do I need special tools to fit the Yokomo Y4-S4A?

No special tools are required beyond common shock servicing items; use a clean workspace and correct shock oil to get best results.

Will this cylinder suit both onroad and offroad use?

While designed for big bore YD-4 shocks, the Y4-S4A benefits handling where smoother damping improves tyre contact; consider your suspension setup when switching disciplines.

What signs indicate the cylinder needs servicing?

Look for increased stiction, oil leakage or changes in damping feel; these signs suggest seals or oil need attention to restore original performance.
