Description
Overview:
This Genuine Stihl rim sprocket kit is a direct-fit drive component for large Stihl petrol chainsaws. Precision‐machined from hardened steel, it transfers power from the clutch to the chain, delivering smooth, consistent drive and reliable chain engagement. The rim size is 3/8 inch pitch (9.53 mm) with 8 teeth, making it suitable for standard 3/8 inch chains used on high‐performance saws. It is designed for demanding work and regular maintenance cycles, helping to keep your saw cutting efficiently and extending the service life of the bar and chain when replaced at proper intervals. Ideal for professional arborists, forestry work, and serious DIY users, it fits models including the Stihl 064 and MS 640 where a 3/8 inch rim sprocket is specified.
