Abstract: A skateboard having one or more truck assemblies configured to eliminate undesired ride characteristics such as hanger-jiggle and wheel bite, without sacrificing the skateboard's steering responsiveness. Each truck assembly includes an axle assembly with a ring-shaped hanger that is confined on a kingpin using a pair of bushings, at least one of which includes an annular flange that projects into an annular gap defined between the hanger and the kingpin. This prevents the hanger from moving laterally relative to the kingpin and thereby eliminates undesired ride characteristics such as hanger-jiggle and wheel bite. In a separate feature of the invention, the skateboard truck assembly further incorporates a low-friction slider plate that enhances the rider's performance of certain maneuvers and at the same time protects other components of the truck assembly from undue wear.
