The XRAY 302143-S X4 CFF Carbon-fiber Fusion Upper Arm is engineered for serious RC enthusiasts who demand precision and performance. Crafted from premium-grade graphite and softer composite materials, this component is designed to significantly enhance your vehicle's grip and side traction, especially on low-traction asphalt and carpet tracks.
XRAY employs a unique manufacturing process that fuses carbon fiber with composite materials to create the CFF suspension arm. This advanced technique results in an upper arm that offers a remarkable balance of flexibility and rigidity. The inner carbon fiber plate determines the arm's hardness and flexibility, while the surrounding composite material ensures controlled flex and rebound, providing consistent handling across all corners.
This upper arm is designed to fit seamlessly on both the front left and rear right sides of your X4 series car. Its soft hardness makes it particularly suitable for very low to low traction environments, offering enhanced mechanical grip and improved side traction. However, users should note that the softer composition may be slightly more susceptible to damage under high-stress conditions.
