The XRAY XB4 2019 ECS 81mm Front Drive Shaft Set with 2.5mm pin is an optional upgrade that 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. The ECS Drive Shafts also help 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, making this a must have upgrade. Package includes the parts to build one driveshaft. Two shafts are needed to upgrade one chassis.
