The XRAY 305308 ECS BB (Ball-Bearing) driveshafts are crafted to refine handling for racers tackling technical tracks. Using HUDY spring steel, they reduce bearing friction versus standard blade shafts, resulting in smoother change of direction and more consistent corner exits. That reduction in drivetrain drag benefits quick manoeuvres.
These 52mm driveshafts suit smaller layouts where steering precision is critical. The compact length improves initial turn-in and supports drivers chasing agility and sharper steering feedback.
Care is simple for the ECS BB shafts. Assemble following normal ECS procedures and apply Hudy Joint Grease (106213) between the small bearings and outdrives to minimise wear and keep rotation smooth.
