Skateboard Bushings
Skateboard trucks usually have two bushings on each truck, one that works as a spring for easy turns, and a smaller one beneath the kingpin that is easily adjusted to adapt the trucks to your riding style. Tighter trucks will give you a stable ride for mastering street tricks, while looser trucks work best for faster turning. Bushings wear out, and it is convenient to replace them after a while to keep your trucks working in top condition.
