ABSTRACT:
An extruded skateboard truck base (11), which has an angled aperture for a cushion (13) on which a hanger (12) rests. A pivot bolt (14) holds hanger (12) to base (11) which allows weight placed on either side of the skateboard (22) to put pressure on cushion (13) thereby shortening the wheelbase on one side and lengthening it on the other, facilitating the turn. A slotted hole (20) in base (11) allows hanger (12) to move up and down on cushion (13) for a smoother ride. The straight down pressure exerted on cushion (13) eliminates the need for any adjusting mechanism.
