The XRAY XCA (Centrifugal‑Axial) High Dynamic Clutch Set (XR338501) is an optional upgrade for the XRAY NT1 platform, including the NT1 and NT1 2009 Spec. Engineered for more dynamic clutch engagement across common racing conditions, it combines lightweight rotating parts with reinforced components for consistent, responsive performance.
