The XRAY 303824 X4 1.4 mm rear anti-roll bar is a targeted tuning part for the X4 2022 chassis. It helps control roll and refines rear traction so you can dial in mid-corner balance.
Mounted in the rear bulkheads with ball-bearings, the bar runs smoothly for predictable reaction to steering inputs. The bearing mounting also supports fast setup swaps between sessions.
Laser-engraved stripes identify the bar thickness instantly, while a simple screw lets you alter bar height to suit different track surfaces and grip levels.
