Tuning-oriented graphite rear arm for YZ-4SF2

Designed as an RC-scale replacement for the YZ-4SF2 platform, this rear suspension arm uses a resin matrix loaded with graphite to increase stiffness compared to stock arms. The result is a sharper chassis response and improved traction during acceleration and cornering in touring car applications.

Key setup details: the inner suspension pin aperture is 3.5mm and the outer aperture is 3.0mm, so confirm pin compatibility during assembly and keep originals if they fit. As a tuning part it reduces rear flex, which affects weight transfer and the suspension behaviour during aggressive driving or when changing damping.

Fit carefully: verify hinge pin alignment and check clearances for slipper systems or body mounts that could contact the stiffer arm. A conservative installation process is recommended—fit one side first to evaluate handling shifts, then adjust shock and anti-roll settings to restore balance.

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.

Will swapping to the S4-008R5G require changes to my shock setup?

Yes, expect a change in rear response with the stiffer arm. Start with small increases in rear damping or tweak anti-roll bars to regain balance, testing progressively after fitting one side first.

What are the hinge pin hole measurements on this arm?

The inner hole is 3.5mm and the outer hole is 3.0mm. Verify your hinge pins match these sizes before full assembly to avoid fitment issues.
