11190071003 Stihl Rim and Sprocket 3/8 x7 tooth

Stihl rim and sprocket systems are designed to deliver smooth, efficient power transfer from the clutch to the chain while offering improved durability and serviceability over traditional spur sprockets.

Unlike spur sprockets, which are a single-piece unit, rim sprockets use a replaceable rim that sits on a separate drum. This design allows the rim to be changed independently when worn, reducing overall maintenance costs and extending the life of the clutch drum.

Rim sprocket systems also provide better chain alignment and more consistent power delivery, helping to reduce vibration and wear on the bar and chain. This makes them a preferred choice for professional users and those looking for improved performance and longevity from their chainsaw.

Ideal for both professional and domestic applications, rim and sprocket setups are a practical upgrade for maintaining efficient cutting performance and reducing long-term running costs.
