The ECS BB (Ball-Bearing) driveshafts provide a significant performance gain on the standard blade-type driveshafts. The friction involving the driveshaft together with outdrive is paid down, which helps give a smoother managing feel, especially on quick direction modifications, such as chicanes. The reduced friction helps to increase cornering speeds. We suggest the smaller 58mm shafts for smaller, more technical tracks, in which more initial steering is necessary. Drive shafts are exclusively manufactured from special world-renowned, top-secret, self-developed HUDY Spring Steel. Maintenance of those bearing driveshafts is essential, but very simple. Develop them while you would your normal ECS driveshafts, however with the next addition; we recommend utilizing the Hudy Joint Grease (106213) between the tiny bearings additionally the outdrives, for an extended life of this components.
