Refined Engineering for X4 Chassis

The XRAY 305178 X4 Composite Solid Axle 38T is built for X4 cars, delivering a lighter assembly that improves weight balance while retaining strength. Made from XRAY composite, the axle cuts rotating mass to help handling without compromising durability.

Centered Front Belt Geometry

The reshaped axle profile allows the front belt to sit closer to centre, improving forward traction and delivering steadier handling through fast direction changes. This refined belt path helps drivers post more consistent lap times on asphalt and carpet tracks.

Track-Focused Advantages

On the X4 platform this axle reduces unsprung weight and sharpens front-end response, aiding corner entry and mid-corner stability. It is a practical upgrade for racers tuning handling and straight-line grip.
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 the XRAY 305178 fit other X4 submodels?

This axle is purpose made for the X4 family. While some X4 variants share mounting points, always check your chassis spec before fitting to ensure compatibility.

Do I need to change belts or pulleys when installing?

Most stock belts and pulleys will work, but verify belt tension and tracking after installation. Small adjustments to belt routing or tension can optimise performance.

Is the composite axle durable for high-power setups?

XRAY composite offers good strength for typical race motors and sensored brushless systems. For extreme torque or frequent impacts inspect the axle regularly and consider reinforced options if needed.
