Carbon-Fibre Fusion Rear Lower Arm for XRAY X4

The XRAY 303180-H CFF Carbon-Fiber Fusion Rear Lower Arm is purpose-built for the XRAY X4 chassis. The right-side arm fuses a carbon fiber core with a composite shell to deliver a lightweight, durable suspension link for competitive track use.

Controlled Flex for Consistent Lap Times

With the inner carbon plate dictating stiffness and the surrounding composite tuning the flex profile, this arm gives repeatable handling and controlled rebound behaviour that helps drivers nail consistent lap times.

Engineered for High Traction Tracks

As the hard option, this rear lower arm is tailored to carpet and high-grip asphalt where sharper turn-in and less rear collapse is needed compared to softer variants.

Right-Side Fitment and Installation Tips

Configured as a direct-fit right-side component for the XRAY X4, the arm installs using existing mounting points. Tighten hardware to recommended torque and verify suspension geometry after fitting.
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.

Is special hardware required to fit the XRAY 303180-H?

No special fasteners are normally required; the arm uses standard XRAY X4 mounting hardware. Replace worn pins or bushings during the swap for best results.

How does this arm affect corner entry?

The harder arm increases front bite stability and gives crisper corner entry, reducing the tendency to bog down in tight corners on grippy surfaces.

Should I adjust camber or toe after installation?

Check camber and toe after fitting since the change in arm stiffness can alter roll behaviour. Small camber or toe tweaks can help restore desired tyre contact patch.
