The XRAY 305316 X4 ECS Bb Drive Shaft 58mm Hudy Spring Steel (2) provides a direct upgrade path from conventional blade-style drive components. Built from Hudy spring steel, the pair improves drivetrain stability and gives a firmer feel through turns.
The ECS BB configuration places bearings between the driveshaft and outdrive to lower friction and rotational resistance. The result is more consistent cornering speed and cleaner transitions when changing direction at pace.
Keeping the shafts in good order is quick and effective. Assemble as standard ECS driveshafts, then apply Hudy Joint Grease (106213) between the small bearings and the outdrives to limit wear and preserve smooth movement.
