Tune Your X4 with the 1.4mm Rear Anti-Roll Bar

The XRAY X4 1.4mm rear anti-roll bar is a precise tuning part intended to stabilise the rear end and sharpen cornering behaviour. The under-arm mounting reduces the centre of gravity and helps the car remain composed through bends.

Fast Installation and Stable Bearings

Mounting uses bearings at the bulkheads so the bar turns freely while remaining firmly located. This arrangement simplifies changes and keeps tuning consistent between runs.

Thickness Markings and Fine Height Control

Laser-etched stripes identify the bar gauge instantly and a threaded height adjuster lets you tailor roll stiffness to tyre grip and track layout.
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.

What is the main benefit of this 1.4mm bar?

The 1.4mm bar gives a noticeable reduction in rear body roll, which helps maintain stability during cornering and improves predictability.

Do I need special bearings to use it?

Standard quality bearings are sufficient; replace any worn bearings to keep rotation smooth and prevent binding.

How often should I check the height setting?

Check the screw height after a few runs and after transport; vibrations can shift the setting so a quick inspection keeps handling consistent.

Can this bar be used with different rear shocks?

Yes, it works with standard X4 shock setups, but when you change shock rates you should re-evaluate anti-roll bar settings to maintain balance.

How do I keep the laser stripes readable?

Wipe the bar with a soft cloth and avoid aggressive solvents; gentle cleaning preserves the laser etching for quick identification.
