ABSTRACT:
A skateboard truck is presented that includes a kingpin situated between a pivot pin and an axle. The truck includes a base plate, with a pivot pin with a tip pivotally attached with the base plate. An axle having a center point is included, where a pin-axle axis runs from the pivot pin tip through the center point. A kingpin couples the axle with the base plate. The kingpin has a midpoint and a length, with a kingpin axis running the length of the kingpin and through the midpoint. The kingpin midpoint is positioned between the axle and the pivot pin, such that a pin-kingpin axis runs from the pivot pin tip through the midpoint of the kingpin. The pivot pin and the axle are configured such that the pin-kingpin axis is between the kingpin axis and the pin-axle axis, providing the skateboard truck movement about two axes of rotation.
