Part Number - 305333
New extra-strong ECS drive shafts. 50mm ECS set with new reinforced drive shaft, drive shaft case, and drive axle. The 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 to prevent 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 & precise, and easier to drive.
With the ECS drive shafts, wheel vibrations and noise are decreased to a minimum, steering is increased, and cornering speed and smoothness are noticeably increased.
It is very important to regularly service the shafts in order to increase the lifespan and maintain performance. Before use, these steps MUST be followed: 1. Assemble the ECS drive shaft. 2. Use #106210 HUDY Graphite Grease to lubricate both drive shaft couplings. 3. Use medium-grade thread lock (e.g., Loctite 242) on both setscrews. Do not use too much thread lock as it may block the drive shaft. 4. Ensure that the ECS drive shaft moves freely.
