XRAY X4-2025 Composite Links Upper Control Arm 4.9mm (1+1+1+1) XR-302670

The XRAY X4 2025 composite upper control arms deliver the perfect balance of strength and flex for competitive touring car racing. These 4.9mm thick arms use an advanced composite material that absorbs impacts while maintaining precise suspension geometry under hard cornering and acceleration.

The unique 1+1+1+1 configuration refers to the layup pattern that gives these arms their distinctive flex characteristics. This design allows the suspension to work smoothly over bumps and through high speed sections while keeping the chassis stable when you need it most. You'll notice improved mechanical grip and more predictable handling as the arms flex just enough to keep your tires planted without going soft.

Each arm is molded to exacting standards with reinforced mounting points that resist wear from repeated suspension cycles. The composite construction keeps weight low compared to aluminum alternatives, which helps reduce unsprung mass and improves suspension response. These arms are designed to handle the demands of racing while giving you consistent performance lap after lap.

The 4.9mm thickness hits the sweet spot for most track conditions and driving styles. Whether you're running on high grip carpet or lower traction asphalt, these arms provide a solid foundation for your suspension setup. They work seamlessly with the rest of the X4 2025 geometry to give you the control and confidence you need when racing at the limit.

XRAY's composite technology has been refined through years of racing development. These upper control arms are a direct fit for the X4 2025 chassis and come ready to install. When you're building or maintaining your touring car, using quality components like these ensures your suspension performs exactly as intended.
