The Yokomo S4-008F2GA is a direct-replacement graphite front suspension arm developed for the YZ-4SF2 chassis. Its graphite-containing resin construction raises component stiffness, producing clearer steering input and improved traction on a range of surfaces. The part retains inner pin holes of Φ3.5mm and outer pin holes of Φ2.5mm to preserve precise suspension geometry.
Graphite-enhanced resin offers higher rigidity than standard compounds, translating to sharper handling and better feedback at the wheel. Drivers will notice reduced flex under load, which helps maintain line consistency through corners.
This arm is compatible with chassis types such as B-YZ4SF2-1, MOR-010, and MOR-020 and installs using the stock mounting points. No trimming or extra hardware is typically necessary for a clean swap.
