The Spinlock Ceramic Cam Module is a replacement CAM designed for XTS and XCS clutches, suitable for use with ropes measuring 8mm - 14mm (5/16" - 9/16"). The Ceramic coating is specifically made for ropes with blended covers made of materials such as Aramid, Technora, Codura or Vectran, and delivers exceptional resistance against polishing and wear caused by loaded ropes at high line speeds. Additionally, the Ceramic coating allows for quicker engagement onto loaded lines. **Please note: X-BASEC CERAMIC Base is required for installation.
