Track Tuning with the Yokomo S4-412BA

The Yokomo S4-412BA is designed to slot into a 2.0mm hole and act as the joint between stabiliser and suspension arm on YZ-4S cars. Its precise fit keeps the stabiliser positioned correctly so handling remains repeatable across runs.

Compatibility and Role

Delivered as two complete link assemblies, this item suits YZ-4S maintenance and minor upgrades. It works with various Yokomo frames such as B-YZ4SF and MOR-010 and supports smoother transitions through high speed sections.
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.

Can I use these sway bar balls on other Yokomo models?

They are primarily sized for YZ-4S style linkages, but may fit other Yokomo chassis that accept a 2.0mm ball. Check your chassis specs before fitting.

How many link assemblies are included?

The package contains two complete sway bar ball assemblies, giving you a front or rear swap option.

Any tips for installation in tight suspension setups?

Use a fine driver and hold the ball during screw insertion to avoid cross threading. Confirm free movement of the link after tightening.

Will this change handling dramatically?

It provides a subtle yet reliable pivot point; handling changes depend on your overall sway bar setup rather than this part alone.
