Improve Rear Roll Control for the X4

The XRAY 303821 - X4 Anti-roll Bar in 1.1 mm thickness is produced for the X4 2022 family to enhance rear suspension stability. It bolts into the rear suspension arms to deliver crisper handling and better mid-corner balance.

External Bearings for Reliable Movement

Fitted with a ball-bearing mounting, the bar offers low-resistance rotation and precise feedback. Bearings are mounted externally on the rear bulkheads, enabling straightforward replacements and quick adjustment procedures that keep setup time down.

Visible Markings and Screw Height Adjustment

The bar carries laser-engraved stripes that identify thickness at a glance, useful when swapping parts during a race meeting. Height adjustment is via a screw mechanism so you can alter roll characteristics in fine increments without major teardown.
