Skateboard trucks are the metal components that connect the skateboard deck to the wheels. They consist of a baseplate, hanger, and axle, allowing the skateboard to turn and maneuver. The width of the trucks typically matches the width of the skateboard deck for optimal performance. Trucks come in various sizes and materials, affecting the skateboard's stability and responsiveness. Skateboarders can choose between different types of trucks, such as high, mid, or low, depending on their riding style and preferences. Properly adjusted trucks enhance the overall skateboarding experience, making tricks and turns easier to execute.
