Longer 115 mm rear universal central drive shaft used in combination with longer framework #351114. CNC-machined from world-renowned HUDY Spring Steel. Means more free movement of this drivetrain and improves traction. Strategically-machined, lightweight drive shaft has been weight-reduced without compromising energy. Hand ground for maximum precision, then independently calculated and examined. Probably the most unique no-compromise off-road drive shafts.
