The unique XRAY ECS Drive Shaft equalizes the speed between the drive shaft and the wheel. With a unique 2-piece joint between the axle and the wheel, the same extreme wheel turning angle is divided into two shallower angles without joint binding. This means that at the same cornering speed, the inner wheel will not bind or vibrate. Drive through the corner is more stable, more precise, and easier to drive. When used in rear the ECS drive shafts help to improve traction as well. The ECS Drive Shafts help also with improved landing after jumps. With the ECS drive shafts, wheel vibrations and noise are decreased to minimum, steering is increased, stability of the car is increased and cornering speed and smoothness are noticeably increased as well.
