The ECS BB (Ball-Bearing) driveshafts provide a significant performance gain in the standard blade-type driveshafts. The friction concerning the driveshaft and outdrive is paid off, which helps provide a smoother managing feel, particularly on fast way alterations, such as chicanes. The reduced friction helps you to increase cornering speeds. We recommend the smaller 58mm shafts for smaller, more technical tracks, by which more initial steering is necessary. Drive shafts are exclusively manufactured from special world-renowned, top-secret, self-developed HUDY Spring metal. Repair of the bearing driveshafts is essential, but simple. Develop them as you would your normal ECS driveshafts, nonetheless with the next addition; we suggest using the Hudy Joint Grease (106213) between the small bearings and also the outdrives, for a long life of the components.
