XRAY 305308 52mm ECS Ball-Bearing Driveshaft Upgrade  [XR-305308]

XRAY ECS BB Driveshafts for Improved Cornering

The XRAY 305308 ECS BB (Ball-Bearing) driveshafts are aimed at improving handling precision on twisty circuits. Forged from HUDY spring steel, they reduce internal friction compared with blade-style driveshafts, giving smoother rotation and steadier corner speed. That helps when attacking sequences that require quick directional changes.

Best for Tight Corner Work

With a 52mm length, these driveshafts are suited to tighter tracks where small steering inputs matter. The reduced length sharpens initial steering feel and aids drivers chasing consistent turn-in behaviour.

Simple Servicing Steps

Maintaining the ECS BB driveshafts is easy. Assemble them as you would other ECS driveshafts and add Hudy Joint Grease (106213) between the small bearings and outdrives. Doing this preserves smooth operation and extends service intervals.
