XRay ECS BB Drive Shaft 53mm Set - Hudy Spring Steel

The XRay ECS BB Drive Shaft 53mm Set (XR305309) in Hudy Spring Steel delivers a notable handling upgrade by minimising friction between the driveshaft and outdrive. The ball-bearing ECS design promotes a smoother feel, particularly through rapid direction changes such as chicanes, and helps increase overall cornering speed.

Optimised for more open, flowing track layouts, the 53mm length offers slightly reduced initial steering response while improving mid-corner and on-power steering. This balanced behaviour can enhance confidence and precision when pushing for consistent lap times.

Performance Benefits

• Reduced friction between driveshaft and outdrive for smoother handling
• Improved stability in fast direction changes (e.g., chicanes)
• Helps increase cornering speeds
• 53mm length suits open and flowing layouts
• Slightly less initial steering with better mid-corner and on-power steering

Setup & Maintenance

• Assemble as standard ECS driveshafts
• Apply Hudy Joint Grease (106213) between the small bearings and the outdrives to prolong component life
