52mm ECS ball-bearing drive shaft made from world-renowned HUDY Spring Steel. This race-quality drive shaft is a spare part for #305308 ECS BB (Ball-Bearing) Drive Shaft 52mm - HUDY Spring Steel. The ECS BB (Ball-Bearing) driveshafts offer a significant performance gain over the standard blade-type driveshafts. The friction between the driveshaft and the outdrive is greatly reduced, which helps to give a much smoother handling feel, especially on fast direction changes, such as chicanes. The reduced friction helps to increase cornering speeds. We recommend the shorter 52mm shafts for smaller, more technical tracks, where more initial steering is needed. Maintenance of these bearing driveshafts is necessary, but very simple. Build them as you would your normal ECS driveshafts, but with the following addition; we recommend using the Hudy Joint Grease (106213) between the small bearings and the outdrives, for a prolonged life of the parts.
