Description
Overview:
This AV spring is a Genuine Stihl part for selected petrol chainsaws, including the MS 311 and MS 391. It is a compact coil spring made from high‐tensile spring steel, designed to sit within the anti‐vibration system between the engine unit and the handle assembly. Its job is to absorb and isolate engine vibration, improving user comfort and helping to protect the machine from excess shock during cutting. By keeping vibration levels down, it supports smoother control and more consistent cutting performance, especially during longer tasks. Built to OEM specification under Stihl's quality standards, it offers a direct replacement that restores the original feel of the saw when the old spring is worn, stretched, or broken.
Key Features:
- Genuine Stihl OEM component for correct fit and function
- Tough spring-steel construction for long service life
- Helps reduce hand-arm vibration for improved comfort and control
- Stable handling during felling, snedding, and firewood cutting
- Maintains the integrity of the saw's anti‐vibration system
- Direct replacement part to restore performance after wear
- Supports reduced operator fatigue over extended use
- Consistent performance in cold, wet, and dusty site conditions
- Simple, straightforward fitment with standard workshop tools
- Compatible with a range of mid‐to‐large Stihl chainsaws
Typical Applications:
Used in routine maintenance or repairs when vibration increases, the handle feels harsh, or the original spring shows damage. Suitable for arborists, forestry workers, landscapers, and firewood users who need a reliable anti‐vibration setup for regular felling, cross‐cutting, and storm clean‐up work.
