Tune steering onset with YX-39SG on YR-X12

The Yokomo YX-39SG springs are provided as a pair of gold 3.5-volume units intended specifically for the front push rod on 1/12 competition cars. They let you tune steering feel and front roll characteristics without swapping structural components.

Install them at the push rod position to evaluate changes in initial turn-in and roll resistance on dedicated race setups. Swap springs in controlled tests and record results to identify the optimal setting.

Installation is routine for experienced model technicians: remove the necessary front linkage, change the spring while preserving the washer and retainer order, and verify free push rod movement across full suspension travel prior to 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.

What does the 3.5 volume rating mean for handling?

The 3.5 volume rating indicates the spring stiffness relative to other available options and will influence roll and steering onset when used on the front push rod.

Can I test different springs quickly between runs?

Yes. Swap springs while keeping detailed notes on side, orientation, and lap feedback to isolate the effect of this change on handling.

Any final checks after fitting?

Confirm washers and retainers are seated correctly and verify unobstructed push rod travel through suspension movement before track use.
