Track-Focused Upgrade for the YZ-4S with Yokomo S4-008RL5A

The Yokomo S4-008RL5A Rear Suspension Arm is tailored to the YZ-4S chassis to improve fitment and handling on grippy circuits. Molded from graphite and measuring 1mm longer than the RS4 version, it alters roll behaviour and aids sharper corner entry. It is intended for serious racers seeking a durable component that still allows enough flex for fine tuning.
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 swap this arm onto older YZ-4S builds?

Most YZ-4S generations will accept this arm but verify mounting points and hardware length before fitting, as some early builds may need small adjustments.

Is the graphite arm fragile under hard use?

The graphite used is selected for strength and lightness, yet like all composite parts it can crack under extreme impact. Inspect after heavy contacts and replace if damage is visible.

How does the extra 1mm length affect setup?

The 1mm increase compared to the RS4 part shifts roll centre and can reduce mid-corner understeer. Adjust droop and roll centres gradually while testing to find the right balance for your surface.
