The XRAY X4 CFF Carbon Fiber Fusion Left Rear Lower Arm is manufactured using a unique and elegant engineering achievement that looks great and performs even better on the track. Using XRAY's own manufacturing process, a carbon fiber arm and composite arm are molded together using a fusion process to create the CFF suspension arm. This "medium hardness" lower arm will fit the rear left position.
The benefits of the CFF arms are tremendous. The thickness of the inner carbon fiber plate determines the hardness and flex of the arm. The composite around the carbon helps control its flex and rebound, resulting in a very consistent feel from corner to corner. Machined and molded from premium-grade graphite and composite materials, the arm is super lightweight and very compact.
