XRAY 302134-XS X4 CFF Soft Compound Upper Arm Front/RL  [XR-302134-XS]

Refine XRAY X4 Handling for Low Grip Tracks

For drivers chasing more traction on slippery surfaces, the XRAY 302134-XS CFF Upper Arm in extra soft is a purposeful upgrade. The reduced-carbon thickness increases mechanical grip and side bite, which benefits performance on low traction carpet and tarmac.

Geometry That Enhances Control

The arm is formed to sit around the inner shock position, preserving clearance while keeping useful stiffness. That geometry improves steering precision and increases both forward and lateral traction. CFF construction also reduces radial slack for reliable handling.

Use Cases and Cautions

Suitable for the front right and rear left positions on the XRAY X4, this soft arm shines on very low grip layouts. Be aware that the softer material is less resistant to strong impacts than standard arms.
