1/12 pitching damper coil for YR-X12 chassis

This black shock spring, stamped volume 5.0, is intended for pitching dampers on 1/12-scale competition on-road cars and serves as a direct replacement for YR-X12-series pitching springs. It provides a discrete spring element to influence nose dive and pitch reaction under acceleration and braking.

Installation follows standard damper service practice: split the pitching damper, remove the old spring, fit the Yokomo YX-40SBK into the retainer, then reassemble and verify free travel. You will only need common damper tools to complete the swap.

Use the YX-40SBK as part of an overall tuning plan; its volume 5.0 classification indicates its intended stiffness range within Yokomo spring options. Adjust damper oil and piston selections in combination with this spring to refine front-end balance.

Compatibility

  • YR-X12
  • YR-X1219
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.

What tools do I need to fit the YX-40SBK spring?

Standard damper service tools such as small screwdrivers, snap ring pliers, and a clean work area are sufficient. No specialised equipment is necessary to replace the pitching spring.

Should I change other damper parts when installing this spring?

Not mandatory, but reviewing piston choice and oil viscosity is advised. The YX-40SBK will interact with these settings, so coordinated changes can improve handling outcomes.
