1/12 front push rod spring for YR-X12 series

The Yokomo YX-39SG springs are intended for use in the front push rod assembly of 1/12 competition cars, supplied as two gold 3.5-volume springs to assist with fine front-end setup changes.

They are useful for tuning roll behavior and the initial steering feel on purpose-built 1/12 race cars. Fit them in the push rod position and alternate sets during setup to assess handling differences, keeping careful records of orientation and side.

Installation requires basic assembly work: remove the front linkage as needed, swap the spring while keeping washer and retainer order intact, and check that the push rod moves freely through the full suspension cycle before running laps.

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 exactly comes in the box?

The package contains two gold-coloured push rod springs labelled as 3.5 volumes, intended for front-end tuning on compatible Yokomo chassis.

Are these compatible with YR-X1219 as well?

Yes, the springs are listed as compatible with both YR-X12 and YR-X1219, but confirm push rod geometry and retainer fit before committing to a race setup.

How should I approach testing these on track?

Run controlled tests, change only the spring parameter between runs, and log steering and roll feedback to determine if the 3.5-volume spring improves your car balance.
