XRay X4 Anti-Roll Bar - Rear 1.1 mm

The XRay X4 Anti-Roll Bar - Rear 1.1 mm (XR303821) is engineered for the ball-bearing roll bar mounting system and redesigned to work with the X4 rear suspension arms. It mounts to the rear bulkheads via bearings from the outside for extra-smooth movement and quick, easy changes and adjustment. The bar rotates in ball-bearings for maximum precision and free movement, while anti-roll bar height is adjustable via a screw for fast trackside tuning. Laser-engraved stripes indicate bar thickness for simple identification.
