Genuine STIHL drive sprocket designed to transfer engine torque from the clutch drum to the saw chain. Precision-machined to OEM standards, this sprocket delivers smooth engagement with 3/8″ low-profile (Picco ®) chains and is a common wear replacement on many STIHL chainsaws.
Replacing a worn sprocket improves cutting performance, reduces vibration, and prolongs the life of chains and bars on active saws.
