Precise spring preload with the Yokomo S4-S4AJ13

The Yokomo S4-S4AJ13 13mm spring adjustment nut is made for RC tuners who need accurate control over suspension settings. It fits the SO/MO2.0 series and lets you tweak shock preload without major disassembly.

Control spring tension on big bore shocks

Adjusting spring tension affects how the car reacts under cornering and on jump landings. The S4-S4AJ13 provides repeatable perch changes so you can compare setups and find the most consistent lap times.

Chassis fit and practical use

This part is intended for SOR-020, MOR-020, and SOR-020D chassis models. Use it to fine tune for softer grip surfaces or firmer responses on higher traction tracks while keeping original shock internals intact.
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.

Does the S4-S4AJ13 require any special tools?

A standard 13mm spanner or socket is usually all you need to set the nut. Use gentle force to avoid damaging the threads and confirm free movement of the spring perch.

What handling changes should I expect?

Increasing preload will raise ride height slightly and firm up initial spring response, reducing squat and roll. Reducing preload gives a softer initial feel and more compliance.

Any corrosion prevention advice?

Keep the nut and mating threads clean and lightly lubricated. After wet runs, dry and apply a small amount of corrosion inhibitor to prolong service life.
