Description
Overview:
This chain sprocket is a non-genuine replacement part for Stihl petrol chainsaws, built to drive a 3/8 inch (9.5 mm) pitch chain with a 7-tooth profile. Made from durable, hardened steel in a compact round form, it transfers power from the clutch to the chain for smooth, reliable cutting. It is suitable for routine maintenance or replacing a worn sprocket to restore performance and reduce premature chain wear. Designed to match the fit and function of the original component on popular models such as the Stihl MS390 and 036, it helps keep your saw operating efficiently on site, in the workshop, or in the garden.

- 3/8 inch (9.5 mm) pitch, 7-tooth sprocket for correct chain compatibility
