A skateboard truck comprising a base attachable to the underside of a skateboard and an arm carried by the base and rotatable relative to the base about a first axis. An axle having a pair of wheels mounted at opposite ends thereof is carried by the arm and the axle is rotatable relative to the arm about a second axis. A spring-loaded linkage is operatively connected between the base and the arm for limiting the rotational motion of the arm and biasing the arm towards a center position aligned with the skateboard's direction of movement. The first and second axes provide pivoting of the skateboard in two dimensions.
