Spring for the pitching damper on 1/12 YR-X12

This shock spring is made for the pitching damper on 1/12-scale competition on-road cars, supplied in a black finish and marked with volume 5.0. It serves as a direct replacement spring for pitching-type dampers on the YR-X12 series, providing a defined mechanical element in the damper assembly used to control nose dive and pitch response during acceleration and braking.

Installation is straightforward for anyone familiar with 1/12 dampers: disassemble the pitching damper, remove the original spring, seat the Yokomo YX-40SBK spring in the spring retainer, then reassemble and check free movement before track use. No special tools are required beyond standard damper service tools.

From a tuning perspective, the YX-40SBK spring functions as one adjustable node in the front pitch control strategy; its volume 5.0 rating identifies its role within Yokomo spring options for the YR-X12 platform. Test it alongside damper oil and piston choices to dial front-end balance and lap feel.

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.

Is the YX-40SBK a direct fit for the YR-X12 pitching damper assembly?

Yes. The YX-40SBK is specified to fit the pitching damper assemblies on the YR-X12 and YR-X1219 without modification when installed as described.

How should I test the volume 5.0 spring on track?

Start with your baseline damper oil and piston, then replace only the pitching spring with the YX-40SBK. Run a series of laps to note changes in nose dive and traction, then adjust oil or piston size to fine tune handling.
