Yokomo S4-412WSA Sway Bar Kit for YZ-4S

Custom made for the YZ-4S, the Yokomo S4-412WSA Soft Sway Bar Set provides selectable bar thicknesses from 1.0mm to 1.5mm. Use these bars to dial in handling on low grip tracks like loose dirt, and fit them to either the front or rear to reduce body roll and improve stability through corners.

Tune Roll and Traction

The Yokomo S4-412WSA sway bars are a practical upgrade for hobbyists wanting precise suspension setup. Swapping between 1.0mm and 1.5mm changes roll stiffness so you can address understeer or oversteer and keep better corner speed as track conditions change.
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.

Which models are compatible with this kit?

This sway bar set is made for the YZ-4S chassis and fits the listed variants B-YZ4SF2-1, MOR-010, MOR-020, and B-YZ4SF.

How do I change stiffness on the car?

Swap the supplied bars or mix different sizes between front and rear to adjust roll resistance; softer bars increase body movement while thicker bars stiffen roll.

Any tips for first time fitting?

Begin with the 1.0mm bars and test on your usual surface, then step up to 1.5mm if you need less roll; ensure endlinks and mount points are secure after installation.
