Description
Overview:
This genuine Stihl torsion spring is a small but critical component used across a wide range of Stihl handheld machines to provide reliable return tension for control mechanisms. Made from durable steel, it helps restore crisp lever and linkage action so your tool operates smoothly and safely. It is designed for Stihl strimmers and brushcutters such as the FR85T and FR85, and is also used in selected FS, FR, HL, HT, FC, KM and other series models. If a spring has lost tension or broken through wear, replacing it with this OEM part helps maintain performance and reduces downtime by returning the mechanism to its intended function and feel.
Key Features:
- Genuine Stihl part for assured fit and function on listed models
- Steel construction for consistent spring force and long service life
- Helps restore proper tension to levers and linkages for smooth operation
- Precision-formed coil and legs for dependable seating and alignment
- Supports safe control response, reducing sticking or sluggish return
- Simple like-for-like replacement with no modifications required
- Suitable for professional and domestic use where frequent cycling occurs
- Cost-effective maintenance item that prevents knock-on wear
Typical Applications:
Used to replace worn or broken torsion/return springs in Stihl strimmers, brushcutters, edgers, hedge trimmers, pole pruners and Kombi tools. Common in throttle or interlock linkages and other small control mechanisms where a controlled return force is required during grounds maintenance, landscaping, estate upkeep, and contractor work.
