XRAY 302144-XS X4 CFF Extra Soft Upper Arm - Cornering Edition  [XR-302144-XS]

Cornering control with XRAY CFF extra soft upper arm

The XRAY 302144-XS upper arm enhances handling on low-traction surfaces like carpet and worn asphalt. Constructed from CFF (Carbon Fiber Fusion), this component delivers controlled give that helps increase forward and side traction.

Engineering for better traction

The extra soft profile uses a slimmer carbon construction to raise mechanical grip and improve side bite. Its geometry is shaped to clear the inner shock without interference, preserving usable travel while aiding steering feel.

Application and trade offs

Designed to mount on the X4 front left and rear right locations, the XRAY 302144-XS reduces radial play for precise steering inputs. The softer material can be more easily damaged in heavy impacts, but for many racers the handling rewards on slippery surfaces make it worthwhile.
