XRay X4 1.3mm Rear Anti-Roll Bar - XR303843

The XRay X4 Anti-Roll Bar Arm – Above Arm Mount – Rear 1.3mm (XR303843) is a genuine tuning component designed for precise handling adjustment on the rear of the X4 platform. The 1.3mm diameter bar provides a defined step in roll stiffness to help balance corner entry and exit, especially when track grip or driving style calls for finer suspension control.

With an above‑arm mounting configuration, this sway bar sits over the rear suspension arms as intended for this layout, supporting predictable chassis behaviour and consistent lap times. The clearly marked part number XR303843 makes identification straightforward when organising your setup options.
