- The Janux “W” truck system.

• Conventional RKP trucks have a high center of gravity and ride high by nature. Low centers of gravity skateboards are preferred since they make it easier to maintain balance and control. At high speeds, a lower center of gravity increases stability and helps rider stay on the board. The axle of the Janux RKP truck is offset in line with the bushing seats. The "W" hanger is the result of this offset's reduction of the center of gravity.
