Yokomo S4-008F2GA Graphite Front Arm Overview

The Yokomo S4-008F2GA Graphite Front Suspension Arm is made to fit the YZ-4SF2 chassis and replaces standard arms for a noticeable handling upgrade. Built from a graphite-infused resin, the component increases surface hardness to sharpen steering response and boost traction across different track surfaces. Inner suspension pin holes are sized at Φ3.5mm and the outer pin holes at Φ2.5mm to maintain accurate alignment under load.

Why Graphite Improves Cornering

Selecting graphite blends adds rigidity compared to plain resin, giving more direct feedback through the steering and faster recovery after turns. That extra stiffness helps keep the front end planted during quick direction changes, which many racers prefer during tight heats.

Fitment Notes and Simple Installation

This arm fits multiple chassis variants including B-YZ4SF2-1, MOR-010, and MOR-020. Installation is straightforward using the factory mount points, so no drilling or trimming is required for a fast swap at the track.
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 will the S4-008F2GA change handling on my YZ-4SF2?

The S4-008F2GA adds front-end stiffness for crisper steering and improved traction, which tends to reduce understeer and give more precise corner entry.

Do I need different suspension pins to use this arm?

No special pins are required if your model uses the standard sizes; the arm has inner pin holes at Φ3.5mm and outer pin holes at Φ2.5mm to match typical setups.

Is this arm compatible with other Yokomo chassis?

Yes, it is compatible with B-YZ4SF2-1, MOR-010, and MOR-020, so it can be used across several YZ-4SF2 derived builds without modification.
