High-precision front ECS drive shaft for XRAY XB4

The XRAY 365223 Front ECS Drive Shaft is engineered to lift the drivetrain strength of XB4 2019 machines. Machined from Hudy Spring Steel and sized at 81mm, this front shaft is aimed at hobbyists who want a durable, race-ready replacement component.

Robust material and CNC accuracy

Every shaft is CNC-machined to tight tolerances to ensure a consistent fit. Hudy Spring Steel brings proven resilience under load, and the integrated 2.5mm pin locks the shaft into place for secure operation without slop.

Lightweight tuning for sharper response

The diff end has been lightened to reduce rotating mass while maintaining structural integrity, helping with faster acceleration and crisper handling when driving at race pace.

Specifications

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

For racers wanting a stronger, lighter front shaft, the XRAY 365223 balances toughness and reduced mass for improved drivetrain performance.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this fit my XB4 2019 without other changes?

This part is made for the XB4 2019 series and installs directly in standard setups that use the OEM front ECS shaft. Check your mounting hardware for wear before fitting.

Can I use this with aftermarket diffs?

Yes, it works with most aftermarket diff assemblies that accept the same shaft dimensions, but verify the 81mm length and pin interface match the diff output.

How should I maintain Hudy Spring Steel parts?

Keep parts clean and lightly lubricated where applicable, inspect pins and mating surfaces for wear, and replace if any bending or excessive scoring appears after heavy use.
