The XRAY 305309 ECS BB drive shafts are built to reduce drivetrain losses and improve handling precision in 1/10 scale touring cars. Fabricated from Hudy Spring Steel, the 53mm shafts favour open, faster tracks where smoothness through transitions is valued.
The ball-bearing ECS configuration decreases friction versus traditional blade drives by separating the shaft motion from the outdrive. This yields smoother directional changes, better control in chicanes, and stronger on-throttle steering through the corner.
With a 53mm length these shafts shine on flowing layouts that reward steady mid-corner behaviour and confident exits. They deliver improved steering during the middle and end of the corner while slightly softening the instant turn-in.
Keep service simple by assembling like standard ECS parts but include Hudy Joint Grease (106213) between the small bearings and the outdrives. Regular greasing and checks will extend component life and keep handling consistent.
