Precision coupling designed for X4 competition cars

The XRAY 305257 ECS BB SC Drive Shaft Coupling is crafted to improve drivetrain accuracy in race setups. Constructed from HUDY Spring Steel, it balances strength with precise machining to reduce unwanted play.

Hand-ground HUDY Spring Steel for reliable service

Using HUDY Spring Steel ensures high fatigue resistance and consistent geometry. The hand-finished surfaces cut friction and help the coupling maintain smooth rotation under race loads.

Specifically matched to the XRAY X4 series

This coupling is tailored for the XRAY X4 family and fits X4 ALU FLEX and X4 GRAFIT 2024 configurations, supporting better drivetrain efficiency and predictable handling.
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.

Is this compatible with X4 GRAFIT 2024?

Yes, the coupling is made to fit both the X4 GRAFIT 2024 and X4 ALU FLEX drivetrain layouts without modification.

Will this reduce drivetrain play?

Yes, the precise machining and material choice help minimise play, resulting in more direct power transfer and improved throttle feel.

Any break in required?

A short running period under light load helps seat mating surfaces. After that, normal track maintenance and inspections are sufficient.
