Xray XB4 anti-roll bars
Xray introduce new optional anti-roll bar wires in several diameters in order to fine-tune the handling characteristic of the buggy. Available from 1.0mm to 1.8mm the bars are made from heat-treated spring steel wire and come with laser-etched size markings for easy identification. Both the front and rear anti-roll bar are interchangeable so there is no specific front or rear wire.
