XRAY 303180-H X4 Hard Right Rear Lower Arm Carbon-Fibre Fusion  [XR-303180-H]

High-Performance CFF Rear Lower Arm for the XRAY X4

The XRAY 303180-H CFF Carbon-Fiber Fusion Rear Lower Arm has been developed for the XRAY X4 chassis. This right-hand arm merges a carbon fibre internal plate with a composite outer to create a stiff yet resilient suspension piece for competitive driving.

Predictable Response from Material Fusion

The combination of inner carbon fibre thickness and composite outer layer gives a measured balance between stiffness and controlled give. That balance helps maintain traction and predictable rebound during fast direction changes.

Preferred for High-Grip Carpet and Asphalt

This hard-spec arm is aimed at high-grip conditions where drivers need smoother cornering and less mid-corner stoppage than with softer arm options.

Fitment for Right Side of X4

Produced as a direct replacement for the right rear lower position on the XRAY X4 chassis, installation is straightforward for those familiar with basic suspension swaps.
