The XRAY 305308 ECS BB (Ball-Bearing) driveshafts are built to refine your car's on-track behaviour. Made from HUDY spring steel, they cut internal friction versus conventional blade driveshafts, producing smoother transitions and steadier corner speed. That reduced drag is useful when you need fast direction shifts through tight sequences.
These 52mm driveshafts suit compact, technical layouts where steering finesse matters. The shorter span sharpens initial turn-in and helps drivers who prioritise nimble response and tight line control.
Servicing the ECS BB driveshafts is simple. Assemble as you would standard ECS parts and apply Hudy Joint Grease (106213) between the small bearings and outdrives. Regular light lubrication keeps play minimal and extends component life.
