A truck according to the present invention includes a hanger dimensioned for insertion of axles upon which wheels are attached. The truck may be configured for attachment to a skateboard. The hanger includes a cutout portion including a key cavity into which a key is positioned. Bushings and a kingpin are also installed onto the hanger. The key when positioned within the key cavity of the hanger confines the pivot of the hanger on a centerline which bisects the hanger. The key may include extending cylindrical tabs which may allow for the hanger to freely swivel about the kingpin passing therethrough without the use of bearing surfaces. The bushings are positioned on the kingpin and on opposite sides of the key and key cavity of the hanger so as to urge the hanger to its center position.
