Precision front ECS shaft built for XRAY XB4 platforms

The XRAY 365223 Front ECS Drive Shaft is a precision replacement designed for XB4 2019 vehicles. Fabricated from Hudy Spring Steel at an 81mm length, it provides a durable option for racers who need consistent drivetrain behaviour.

CNC finish and spring steel durability

CNC machining ensures repeatable fit and true geometry across parts. Hudy Spring Steel is selected for its fatigue resistance, and the 2.5mm pin gives a secure connection to mating components.

Reduced inertia for improved throttle response

By trimming weight at the diff end, rotating mass is reduced to help the car accelerate more responsively while preserving the component's strength for demanding track use.

Specifications

  • Length: 81mm
  • Pin Diameter: 2.5mm
  • Material: Hudy Spring Steel
  • Compatibility: XB4 2019 Series

Combining Hudy Spring Steel toughness with a lightened design, the XRAY 365223 is a practical drivetrain upgrade for serious XB4 drivers.

Does the 2.5mm pin require a special retainer?

The shaft uses a standard 2.5mm locating pin which is secured per the vehicle's original method. Use the correct clip or grub screw specified by your XB4 setup.

Is Hudy Spring Steel prone to corrosion?

Hudy Spring Steel is durable but should be kept clean and dried after exposure to moisture. A light protective oil helps prevent surface rust during storage.

Will this alter my gear mesh?

The shaft itself does not change gear spacing, but ensure correct installation and check for any lateral play that could affect mesh under load.

Can I use this on high-traction surfaces?

Yes, the reduced rotating mass and strong material suit both high-traction and mixed-surface racing, offering more predictable drivetrain behaviour.
