High-Precision Carbon-Fiber Upper Arm

The XRAY 302142-M X4 Carbon-Fiber Fusion Upper Arm layers a stiff carbon insert with a tuned composite shell to deliver reliable feedback on technical layouts. It is engineered to keep handling predictable across a variety of corner speeds.

Layered Construction for Stable Handling

XRAY manufactures the CFF arm by laminating an inner carbon fiber plate into a composite outer. The core thickness determines stiffness and flex point, while the surrounding composite manages rebound and chassis attitude during weight transfer.

Lightweight Profile and Position-Specific Fit

Using premium graphite and composite materials, the XRAY 302142-M upper arm keeps mass low while providing the medium hardness needed for many racing surfaces. Fit it on the front left or rear right to help balance entry and exit behaviour.

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.

Can I swap this arm with stock parts and will geometry change?

Yes, the arm is a direct fit for XRAY X4 models and should not require geometry modification. Always recheck alignment and make small camber or toe tweaks as part of setup tuning.

How durable is the carbon-composite fusion after impacts?

The fused construction improves resistance to repeated loads, but severe impacts can still damage the composite skin or carbon insert. Inspect for cracks or delamination after hard hits and replace if structural integrity is compromised.
