This is an optional XRAY 52mm ECS Drive Shaft with 2mm Pins, and is intended for use with the XRAY T2, T3 and T4 vehicles. XRAY 52mm ECS drive shafts feature 2mm diameter cross pins for improved reliability. Using a unique 2-piece joint between the axle and wheel, the ECS drive shaft equalizes the speed between the drive shaft and the wheel. The same extreme wheel turning angle is divided into two shallower angles and eliminates joint binding so the inner wheel will not bind or vibrate. The drive through the corner is more stable and precise, but also makes the car easier to drive. Package includes the parts needed to build one 52mm drive shaft.
NOTE: To use the ECS drive shafts you need to use the front C-hubs V2 with the larger opening. The C-hubs V2 were included in all T2'008/T3/T4 kits, so owners of the T2, T2'007 and T2R must purchase the C-hubs V2 separately.
