Carbhub Sprocket Clutch Kit 3/8 LP for Stihl MS170-MS250 Chainsaws | Includes Washer & E-Clip

Overview

The Carbhub Sprocket Clutch Kit 3/8 LP is designed to refresh the drivetrain on popular Stihl models. It targets chainsaws within the 017–025 family and covers machines such as MS170, MS180, MS210, MS230, and MS250. This kit bundles essential components to support routine maintenance or a focused overhaul without the need for a full saw rebuild.

Instead of a bare replacement, this kit brings together a clutch assembly, a worm gear, and a 3/8" low‑profile (LP) sprocket. The result is a cohesive set of parts that can help refresh the way power and rotation transfer through the drive system, potentially restoring smoother operation and dependable performance during cutting tasks.
