Fine-Tune XRAY X4 Handling with Extra Soft CFF Arms

RC racers aiming to improve grip on low traction layouts will find the XRAY 302134-XS CFF Upper Arm a practical tuning part. The extra soft version uses thinner carbon to raise mechanical traction and side bite, making it well suited to low traction asphalt and carpet surfaces.

Precision Geometry for Improved Control

The arm profile wraps around the inner shock position to keep proper clearance while maintaining adequate strength. This shape sharpens steering feel and boosts both forward drive and lateral grip. CFF technology reduces radial play and helps deliver consistent handling at the limits.

Fitment and Usage Notes

This component fits the front right and rear left positions on the XRAY X4 and is most effective on very low grip tracks; note that the softer material can be more vulnerable to heavy impacts.
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 extra soft arm suitable for high grip tracks?

The extra soft arm is optimised for low traction surfaces. On high grip tracks a stiffer arm will usually provide better durability and more predictable steering.

Which positions does this part fit on the X4?

This part is designed for the front right and rear left locations on the XRAY X4. Confirm fitment before installation if you run a modified suspension layout.

How can I minimise breakage with softer arms?

Avoid heavy impacts and check arms regularly for hairline cracks. Consider swapping to a harder arm for practice sessions with rough walls or kerbs to reduce the risk of damage.
