Traxxas steel constant velocity driveshafts are designed to handle the extreme horsepower and articulation that a T-Maxx or Revo can deliver. The inner and outer U-joints are lubricated and sealed by a rubber boot for maximum protection against the elements, and the U-joint pins are held captive by a lightweight aluminum sleeve, so you never have to worry about losing a pin. The nickel plated steel shafts, blue silicone boots, and red-anodized aluminum accents not only look good, but they are designed to exacting specifications for ultimate strength and performance. These are simply the most advanced steel CV driveshafts available.
