Optimise Rear Roll Characteristics

The 1.3mm rear anti-roll bar is a practical upgrade for XRAY X4 racers aiming to refine rear traction and rotation. It fits to the rear suspension arms and runs on a ball-bearing mount to ensure low friction and reliable movement.

Fast Installation and Height Adjustment

The external rear bulkhead mount allows for quick installation and straightforward setup changes. Adjusting the bar height is done with a screw, so you can make rapid alterations between heats.

Clear Laser Labels for Diameter

Laser-engraved stripes show the bar diameter, helping you spot the 1.3mm option instantly when organising parts for practice or competition.
Remark :

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 change understeer or oversteer?

Using a stiffer or softer rear bar alters roll distribution; the 1.3mm piece makes subtle changes to rear rotation which can influence understeer and oversteer depending on the rest of your setup.

Are bearings included for the mount?

The design uses a ball-bearing mounted system to reduce friction and provide consistent feel, which helps maintain steady roll response during runs.

How to rotate testing protocol?

Make measured changes, run multiple laps and compare tyre wear and lap consistency to see how the 1.3mm bar affects handling across different track sections.
