A skateboard is provided with trucks, each of which carries a plurality of wheels mounted in independent suspension. Longitudinally extending arms carry the wheel axles forwardly or rearwardly relative to a mounting which secures the arms in rotatable fashion to the trucks. The arms are resiliently biased by means of separate springs or torsion bars so that varying pressures across the skateboard platform alter the distance of the skateboard wheels from the underside of the platform and conversely roadway irregularities displace the skateboard wheels towards the platform independently one from another.

A skateboard truck in which a plurality of wheels are mounted for rotation about axles extending laterally outwardly from a mounting, the improvement wherein said wheels are carried in independent suspension from said mounting and comprising separate longitudinally extending swing arms associated with each axle connected to said mounting and to the axle associated therewith, means for resiliently biasing each of said axles toward a position longitudinally displaced from the interconnection of the associated swing arm with said mounting, said swing arms being rotatably connected to said mounting, said mounting including pivot means for carrying the wheel axis for pivotal movement about an axis inclined in a plane extending longitudinally through the truck for steering action.
