The typical skateboard truck has two bushings on each truck. Bushings are rubber rings found inside the trucks that cushion the trucks when a skateboard turns. The stiffer the bushing the more stable the board. The softer the bushings the easier it is to turn a skateboard.
Be sure to change your bushings frequently in order to keep your skateboard responsive to your personal skateboarding style.
The Venom Super Carve Pack is designed to deliver the ultimate turning experience. Quick turns, tight turns, deep turns. Double conical bushings provide the least possible turn resistance but still have enough spring to keep you on track. Cones: .6″ tall x .93″/.65″ wide.
