Description
Overview:
This Genuine Stihl rim-type drive sprocket kit is a replacement part for Stihl petrol chainsaws configured for 0.325" (8.26 mm) pitch chain. Built from hardened steel for long service life, it restores smooth, accurate chain drive and helps protect the clutch system by allowing the wear component to be replaced as a kit. It is suitable for common mid-range saws used in forestry, landscaping and firewood cutting, including the MS241 C and MS231. By renewing a worn rim sprocket, you maintain correct chain tracking and reduce vibration and skip, which supports safer, cleaner cuts and consistent performance.
