Tuned Steering Control for the X4 Chassis

The XRAY 302144-M X4 CFF Upper Arm is engineered to strike a balance between stiffness and compliance for the inner shock mounting on the X4 chassis. Built with Carbon Fiber Fusion construction, this part sharpens handling precision and delivers predictable steering behavior for competitive drivers.

Grip and Long-Term Strength

With a medium hardness rating, the XRAY CFF Upper Arm improves both forward and lateral traction. Its profile provides the clearance needed for suspension travel while maintaining structural integrity to reduce radial play. The net effect is crisper steering inputs and steadier performance at speed.

Flexible Mounting Positions

This upper arm fits the front left and rear right positions, offering useful adaptability for tuning different handling characteristics. That flexibility makes it a straightforward choice when adjusting balance across varied track surfaces.

A solid option for hobbyists and racers tightening up steering response, the XRAY 302144-M CFF Upper Arm brings measurable traction and control improvements to competitive X4 setups.
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 upper arm work on other XRAY models?

This arm is designed specifically for the X4 chassis inner shock location. Other XRAY models may require modifications or different mounting hardware to fit correctly.

How does medium stiffness affect handling?

Medium stiffness gives a balanced mix of support and compliance, enhancing traction without making the suspension too harsh. It helps maintain predictable turn-in and consistent corner exits.

Any maintenance tips for carbon fiber parts?

Inspect mounting holes and fasteners regularly for wear, clean grit from pivot areas, and replace the arm if you notice cracks or delamination. Proper hardware torque helps avoid premature damage.
