XRAY 303183-G Graphite CFF Rear Lower Arm Left Inner Shock Position  [XR-303183-G]

Tuning XRAY X4 Handling and Traction

If you want crisper handling for your XRAY X4 2025, the XRAY 303183-G CFF Rear Lower Arm is a targeted upgrade. Made using Carbon Fiber Fusion technology blended with graphite, this arm focuses on improving mechanical traction and sharper steering feel on grippy tracks.

Graphite Benefits for High Grip Tracks

The CFF rear lower arm combines controlled flex with stiffness thanks to its graphite build. That balance works well on carpet and high-traction asphalt, helping the car hold lines more predictably. Centering the shock mount in the arm evens out load transfer, which reduces abrupt stalls and lets the car rotate more smoothly through corners.

Fitment Notes and Fast Installation

This component is made for the left side of the XRAY X4 2025 series and matches typical race setups that favour a mid shock location. The graphite hardness makes it durable for repeated setup tweaks and the swap-in process is straightforward so you can get back on track quickly.
