Complete pair of 58mm ECS BB SC drive shaft installation. The ECS BB (Ball-Bearing) driveshafts offer a considerable performance gain in the standard blade-type driveshafts. The friction between driveshaft as the outdrive is paid off, which really helps you to offer a smoother handling feel, specially on fast technique customizations, like chicanes. The paid down friction really enables you to increase cornering prices. Drive shafts are solely made of unique world-renowned, top-secret, self-developed HUDY Spring steel. Repair of the bearing driveshafts is vital, but quite simple. Develop them as you would your normal ECS driveshafts, none the less with one of these addition; we suggest using the Hudy Joint Grease (106213) involving the small bearings along with the outdrives, for an extended life from the elements. The initial Spring Clip System SCS utilizes a drive shaft situation with a C clip groove to secure the aluminum pin retainer. Due to this system, no set screws are expected to recapture the coupler pins, making the ECS assemblies simple and convenient to build, and very dependable. The driveshaft solution life is very long, even though the pins float easily within the bones, ensuring smoother rotation and enhanced cornering rate.
