Dial in your shocks with the Yokomo S4-S4AJ13

The Yokomo S4-S4AJ13 13mm spring adjustment nut lets hobbyists and racers refine suspension preload with simple, reliable adjustments. Compatible with the SO/MO2.0 chassis family, it is useful for tailoring handling to different track conditions.

Micro adjustment for big bore shocks

Precision matters when setting up big bore shocks, and the S4-S4AJ13 offers fine control over spring compression and initial tension. This helps achieve predictable roll and traction without swapping springs or shock internals.

Recommended chassis compatibility

This adjustment nut is built for the SOR-020, MOR-020, and SOR-020D chassis. Use it when you want to soften or stiffen the front or rear with minimal teardown and quick trackside changes.
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 S4-S4AJ13 compatible with older Yokomo shocks?

It is optimised for SO/MO2.0 style shocks and SOR-020/MOR-020 series chassis. Older or non standard shocks may not offer the same adjustment range or secure fit.

Can I change handling simply by adjusting this nut?

Yes. Small changes to spring preload affect body roll and traction. Combine perch adjustment with spring and damper settings for the best result.

Should I check preload after each run?

It is good practice to inspect adjustment and spring height after each session, especially on rough tracks, to keep handling consistent lap to lap.
