58mm ECS ball-bearing drive shaft produced from world-renowned HUDY Spring Steel. This race-quality drive shaft is a supplementary component for #305306 ECS BB (Ball-Bearing) Drive Shaft 58mm - HUDY Spring metal????. couple of 2. The ECS BB (Ball-Bearing) driveshafts offer an important performance gain in the standard blade-type driveshafts. The friction between driveshaft whilst the outdrive is paid down, which allows you to give a smoother handling feel, specially on fast method adjustments, particularly chicanes. The paid down friction helps you to increase cornering rates. Maintenance among these bearing driveshafts is necessary, but simple. Develop them while you would your normal ECS driveshafts, but with another addition; we recommend utilising the Hudy Joint Grease (106213) between the little bearings as well as the outdrives, for an extended life of this components
