YRX 12 Damper Spring Cup and Seal Details

The Yokomo YOKYX40SC is an RC spring cup and O-ring cap specified for YRX 12 pitching damper fitment. It secures the spring location while the O-ring cap provides a sealing interface that reduces oil transfer around the damper shaft, affecting front-to-rear pitch dynamics.

Practical use: the spring cup sets spring seat height and alignment while the O-ring cap helps control internal fluid movement and minimise slack. Verify your YRX 12 damper shaft diameter and spring dimensions match this component before installation, and choose shock oil and springs that suit the chassis balance you want to achieve.

Installation guidance: insert the cup to the required stack, place the spring and compress to engage the O-ring cap so the seal seats without excess preload; confirm smooth shaft operation after assembly. This item is supplied as a 1/10 scale RC tuning accessory only.
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.

How durable is the O-ring seal?

O-ring life depends on material and service conditions; inspect for flattening or cracking after repeated servicing and replace if it no longer provides a reliable seal.

Can this prevent play in older dampers?

The O-ring cap helps take up minor internal clearance and reduces oil migration that can contribute to play, but it will not correct major shaft wear or damaged components.

How should I inspect after installation?

Check for unrestricted shaft travel, confirm the seal engages without binding, and monitor for any changes in pitch response during the first few runs to ensure correct fitment.
