Description
Overview:
This tension spring is a genuine Stihl spare designed to restore and maintain correct tension within the chainsaw mechanism. Made from high‐quality spring steel, it provides reliable, repeatable force to keep moving parts operating smoothly after wear, fatigue, or breakage of the original spring. It is purpose‐built for Stihl professional saws, including the 064 and MS360, ensuring a precise fit without modification. As an OEM part (MPN 1121 160 5500), it helps prevent slack controls and poor adjustment, contributing to consistent performance and safer operation. The compact coil design suits tight assemblies found in these models, making it a practical replacement during routine servicing or repairs where tension, return, or indexing action is required.
