XRay X4 Anti-Roll Bar UAM - Under Arm Mount - Front 1.1 mm

This 1.1 mm front UAM (Under Arm Mount) anti-roll bar, part number XR302831, delivers precise and consistent roll control using a ball-bearing mounted system. The bar rotates freely in bearings for maximum precision, while the under-arm mounting contributes to an ultra-low centre of gravity for responsive touring car handling.

Adjustment is quick and straightforward: a single screw sets bar height, helping you fine-tune chassis balance in minutes. Laser-engraved stripes clearly indicate the bar’s thickness for fast identification in the pit.
