XRAY X4 CFF Upper Arm Extra Soft FL/RR

The XRAY X4 CFF Upper Arm (Inner Shock Position) Extra Soft (XR302144-XS) uses a thinner carbon layup to generate greater mechanical grip and enhanced side bite on low-grip surfaces. Its profile conforms around the inner shock for proper clearance while maintaining strength and precision.

This extra soft option refines steering response and improves both forward and lateral traction. The design enhances durability and eliminates radial play for maximum accuracy and control, delivering the consistent feel associated with CFF (Carbon Fibre Fusion) construction.
