Complete set of 58mm ECS BB SC drive shaft installation. The ECS BB (Ball-Bearing) driveshafts provide a substantial performance gain within the standard blade-type driveshafts. The friction between your driveshaft while the outdrive is reduced, which helps to provide a smoother handling feel, especially on quick way modifications, like chicanes. The paid down friction really helps to increase cornering rates. Drive shafts are exclusively made of unique world-renowned, top-secret, self-developed HUDY Spring metal. Upkeep of those bearing driveshafts is important, but quite simple. Build them while you would your normal ECS driveshafts, however with these addition; we recommend utilizing the Hudy Joint Grease (106213) involving the little bearings as well as the outdrives, for an extended life of the components. The unique Spring Clip System SCS uses a drive shaft case with a C clip groove to secure the aluminum pin retainer. Because of this system, no set screws are needed to recapture the coupler pins, making the ECS assemblies easy and convenient to put together, in addition to extremely dependable. The driveshaft solution life is very long, while the pins float freely within the joints, ensuring smoother rotation and improved cornering speed.
