Front push rod spring tuning for YR-X12

Yokomo YX-39SG gold springs are made for the front push rod on 1/12 competition cars, supplied as a pair and rated 3.5 volumes to aid precise front-end tuning without altering chassis parts.

They are intended to adjust initial steering response and roll characteristics on purpose-built 1/12 race setups; install them in the push rod location and swap to evaluate handling changes, noting side and orientation for accurate comparison.

For installation: remove the front linkage as needed, replace the spring while keeping washer and retainer order, then confirm the push rod moves freely through the full suspension travel before running.

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.

How many springs are included and what is their rating?

The kit includes two gold-colored push rod springs marked as 3.5 volumes for front-end tuning on compatible Yokomo chassis.

Will these fit other 1/12 models besides YR-X12?

They are specified for the YR-X12 series; fit on other 1/12 cars depends on push rod length and whether existing retainers and washers match the spring seating.

Any installation tips to avoid handling errors?

Change one parameter at a time, keep track of side and orientation, and recheck push rod free play and full travel after each swap to isolate handling effects.
