Precision Kashima Cylinder for YD-4 Big Bore Shocks

The Yokomo Y4-S4A Aluminium Shock Cylinder is crafted as an upgrade option for YD-4 big bore shocks, using a Kashima Coat to provide ultra-smooth movement and reduced vibration. That smoother response helps when pairing the car with harder compound tyres to maintain consistent traction.

Consistent Response for Competitive Driving

The Kashima surface treatment lowers friction on moving parts, helping the cylinder resist wear and keep predictable damping over many runs. This is useful for drivers who expect repeatable handling during practice and events.

Specifications

  • Material: Aluminium with Kashima Coat
  • Compatibility: YD-4 big bore shocks
  • Function: Enhances damping smoothness and tyre traction

Recommended for modelers seeking a reliable YD-4 upgrade that improves traction feel and shock durability on varied 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.

Can I reuse my existing pistons with the Y4-S4A?

In many cases the pistons are compatible, but confirm piston size and stroke match the Y4-S4A cylinder to ensure correct damping behaviour.

Does the coating change how often I need to service shocks?

The Kashima Coat can reduce wear, but regular servicing of seals and oil changes is still advised to maintain peak performance.

What oil weight works well with this cylinder?

Oil choice depends on chassis setup and driving surface; start with the oil weight you used previously and adjust incrementally to fine tune body roll and traction.
