XRay X4 CFF Rear Lower Arm - Inner Shock Position - Medium - Left

The XR303183-M CFF Rear Lower Arm (Medium, Left) places the shock in the middle of the arm, distributing load evenly to enhance mechanical traction and improve on-track response. Its Carbon Fiber Fusion construction delivers balanced flex characteristics for confident, predictable handling. Compared with Hard (H) arms, the Medium version is more flexible, helping generate traction in hot conditions and offering a more forgiving drive on asphalt. This piece is for the left side of the rear suspension.
