Traxxas Steel Constant-Velocity Center Driveshafts are designed to handle the extreme horsepower and articulation. 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, they are designed to exacting specifications for ultimate strength and performance. These are simply the most advanced steel CV driveshafts available. Use Traxxas stock and hop-up replacement parts to get the most out of your Traxxas RTR vehicles.
