The ECS BB (Ball-Bearing) driveshafts provide a significant performance gain within the standard blade-type driveshafts. The friction between your driveshaft plus the outdrive is paid down, which helps you to provide a smoother handling feel, especially on quick way changes, such as for example chicanes. The reduced friction helps to increase cornering rates. The 59mm shafts are ideal for more available and moving track designs. They are going to provide slightly less initial steering, but better steering in the center of the corner, as well as on energy. Drive shafts are exclusively made of unique world-renowned, top-secret, self-developed HUDY Spring Steel. Maintenance among these bearing driveshafts is important, but very simple. Develop them as you would your normal ECS driveshafts, however with the following addition; we recommend utilizing the Hudy Joint Grease (106213) involving the tiny bearings as well as the outdrives, for a prolonged life of this components.
