XRAY 303821 X4 Rear Anti-roll Bar 1.1 mm Precision Stabiliser  [XR-303821]

Rear Balance Upgrade for X4 Handling

The XRAY 303821 - X4 Anti-roll Bar in 1.1 mm thickness is a precision replacement part for the X4 2022 range, built to increase rear suspension stability. It fits directly to the rear suspension arms and helps refine the car's handling balance on technical tracks.

Smooth Bearings for Accurate Tweaks

The bar uses a ball-bearing mounting arrangement to deliver low-friction movement and dependable feedback. Bearings sit externally on the rear bulkheads so you can make swift, repeatable adjustments without stripping the layout apart. That setup supports consistent handling and sharper response through turns.

Clear Markings and Height Adjustment

Laser-engraved stripes on the bar denote its thickness for quick identification during setup and spares management. Height is set with a screw-style mount, letting you dial in roll behaviour in small steps while keeping the assembly secure.
