52mm ECS ball-bearing drive shaft produced from world-renowned HUDY Spring Steel. This race-quality drive shaft is an extra component for #305308 ECS BB (Ball-Bearing) Drive Shaft 52mm - HUDY Spring Steel. The ECS BB (Ball-Bearing) driveshafts offer a significant performance gain within the standard blade-type driveshafts. The friction between your driveshaft and also the outdrive is significantly paid off, which really helps to offer a much smoother handling feel, especially on quick direction changes, like chicanes. The reduced friction helps increase cornering rates. We suggest the smaller 52mm shafts for smaller, more technical songs, where more initial steering is required. Maintenance among these bearing driveshafts is essential, but very simple. Develop them as you would your normal ECS driveshafts, however with these addition; we recommend utilizing the Hudy Joint Grease (106213) between your small bearings and also the outdrives, for a prolonged life of this components.
