Tune Your T4 2017 with the XRAY 305521-K Layshaft

The XRAY 305521-K Aluminum Solid Layshaft is tailored for the T4 2017 chassis, combining lightweight aluminium with a durable design to help lower rotational load while retaining rigidity.

Accurate Machining for Less Vibration

Produced using high-precision CNC machining, the layshaft keeps close tolerances for roundness and minimal runout, which helps reduce drivetrain vibration. Its flat mounting face also promotes steady spur gear engagement.

Practical Gains on Track and Road

Reducing rotating mass with this layshaft can sharpen throttle response and handling balance, making it a practical upgrade whether you are tuning for club events or afternoon practice sessions.
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 the XRAY 305521-K compatible with non-2017 T4 variants?

This part is specifically made for the T4 2017 geometry; other T4 generations may require different lay shaft lengths or mounting details.

Will this change gear lash or mesh?

The flat spur mounting surface helps keep gear mesh consistent, but you should reset gear lash after fitting to ensure optimal engagement.

How does weight reduction affect handling?

Lowering rotating mass tends to improve acceleration feel and can make the car turn in sharper, though suspension setup should be checked to balance changes.

Do I need special tools to fit this layshaft?

Basic hobby tools are sufficient; a torque driver and a careful check of spur gear alignment are useful to get a clean installation.
