Front outer hinge pin for YD-4

This is the front outer suspension arm pin used on the YD-4 scale chassis, supplied as a standard replacement part by Yokomo. The component serves as the outer hinge pin on the front suspension arm and is intended for RC-scale maintenance and setup tasks rather than any full-size application.

For maintenance and setup, check suspension geometry and arm alignment after fitting the pin, and verify secure retention with the original clip or retainer used on your chassis. This part affects lateral play at the lower arm outer pivot, so inspect for wear during routine service intervals.
