Yokomo S4-008R5GA Rear Suspension Arm for YZ-4SF2

Upgrade the rear end of a YZ-4SF2 with the Yokomo S4-008R5GA Graphite Rear Suspension Arm. Built from a graphite-loaded resin, the arm is stiffer than typical stock pieces which helps improve handling response and tyre bite on loose or grippy surfaces. It is drilled for a 3.5mm inner suspension pin and a 3.0mm outer suspension pin to secure precise positioning under load.

How does graphite infusion change handling?

Graphite increases part stiffness which reduces flex, delivering quicker steering response and more consistent rear traction through corners.

Does installation need special hardware?

No special hardware is required beyond the specified 3.5mm inner and 3.0mm outer pins; existing compatible pins should fit as listed.

Is this arm suitable for off-road circuits?

Yes, the added stiffness helps the rear of the car maintain traction on both hardpack and loose off-road surfaces, though overall setup may need small shock or toe adjustments.

How to check fitment after fitting?

After assembly, cycle the suspension fully to confirm smooth travel, ensure pin clearance, and recheck screw torque after a short run.
