The XRAY 303824 X4 1.4 mm rear anti-roll bar is a precision tuning component for the X4 2022 chassis. It reduces unwanted roll and helps fine-tune rear-end behaviour for sharper corner exits.
Fitted into the rear bulkheads via ball-bearings, this anti-roll bar moves with minimal friction for steady, repeatable handling inputs. The bearing fit supports quick setup swaps between heats.
Engraved stripes identify thickness at a glance, and an easy-to-access screw provides height adjustment so you can tailor the bar to differing track grip and layout.
