Genuine STIHL drive sprocket (also known as clutch drum / rim sprocket) designed to transfer power from the clutch drum to the cutting chain. Machined to OEM tolerances for smooth engagement with 3/8″ low-profile (LP/Picco) chains, this sprocket provides precise fitment and long service life on compatible STIHL chainsaws.
This component is a common wear item on professional and mid-range saws, and replacing worn or damaged sprockets can greatly improve cutting performance and reduce vibration or premature chain wear.
