Rear arm with graphite reinforcement for YZ-4SF2

This component is an RC-scale replacement targeted at the YZ-4SF2 platform. The part uses a resin compound reinforced with graphite to boost stiffness compared with standard arms, producing sharper chassis feedback and improved traction on both acceleration and through turns in touring car configurations.

Installation and setup notes: inner suspension pin opening is 3.5mm while the outer hole is 3.0mm, so confirm pin fit during installation and consider reusing original pins only if they match. The arm is intended as a tuning upgrade to cut rear flex, which will influence weight transfer and the behaviour of the rear suspension under heavy inputs or after damping changes.

During fitment check hinge pin alignment and ensure there is sufficient clearance around slipper clutches and body mounts that could contact a stiffer arm. Adopt a stepwise approach: replace one side first to judge handling, then retune shock and anti-roll settings to reconcile the altered rear behaviour.

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.

How does the graphite content change durability and feel?

Graphite reinforcement raises part stiffness, delivering firmer feedback and reduced rear flex. This typically improves traction but may transfer more load to other suspension components, so monitor wear and retune damping as required.

Can I reuse my existing hinge pins with this arm?

Check pin diameters before installation: the inner hole is 3.5mm and the outer hole is 3.0mm. If your original pins seat cleanly, they can be reused; otherwise source matching pins to ensure correct fitment.
