The XRAY 303822 - X4 Rear Anti-roll Bar at 1.2mm is a tidy upgrade for pilots aiming to sharpen rear behaviour in turns. It helps control roll without changing core suspension geometry, so handling feels cleaner through the mid corner.
Designed to interface with the X4 rear arms, the bar runs on ball-bearings in the rear bulkheads to minimise friction. That smooth rotation makes roll adjustments predictable when you are refining balance.
Adjusting height is straightforward using the exposed screw points, allowing quick changes during practice. The laser-etched stripes make the 1.2mm bar easy to spot among your spares, reducing pit lane downtime.
