Firm upper link to stabilise front suspension

This hard upper A-arm is an RC-scale accessory designed for Yokomo R12 and GT family cars. The part uses a tougher resin than common stock arms, which reduces play in the upper arm under lateral loads and helps the suspension remain composed through corners. It is intended as a tuning option to sharpen steering feedback and curb unpredictable arm motion at higher speeds.

Installation follows typical A-arm service practices: ensure contact surfaces are clean, check ball joint and hinge-pin clearance, and confirm equal fitment on both sides. Because the part stiffens the upper link, you will get a firmer front-end response without altering the basic mounting geometry.

Which chassis does this suit best?

The arm is designed to fit Yokomo R12 and GT family models listed above; verify part numbers against your car before ordering to ensure compatibility.

Is left/right orientation important?

Yes, install arms symmetrically and check that ball studs and hinge pins provide equal clearance each side to avoid uneven suspension behaviour.

Can this be used on competition cars?

It is suitable as a tuning upgrade for competition where a firmer front-end is desired; test on-track to confirm it matches your setup and driving style.
