Stability Upgrade for Precise Cornering

The XRAY 303831 X4 Rear Anti-Roll Bar is a precision part developed to cut body roll and sharpen handling on the track. Built for the X4 platform, this 1.1mm bar helps drivers dial in consistent cornering balance.

Low Center Integration and Smooth Movement

This anti-roll bar mounts to the lower suspension arms for a neat layout that supports a low center of gravity. Ball-bearing mounts at the bulkheads allow smooth, accurate rotation and help maintain consistent performance under load.

Quick Identification and Fast Adjustment

Laser-engraved stripes clearly show the bar thickness so you can pick the right unit at a glance. The bar height is adjusted with a simple screw mechanism, making setup changes quick between heats or track layouts.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this fit every X4 variant?

Yes. The XRAY 303831 is made to be compatible across the X4 range when installed as specified in the kit instructions.

How does bar thickness change handling?

A thicker bar increases roll stiffness at the rear, reducing body roll and promoting quicker transitions through corners.

Any tips for setup tuning?

Start with the stock position, then change bar height and thickness in small steps while testing to find the best balance for your surface and driving style.
