Description
Overview:
This anti-vibration spring is a replacement steel helical spring used in the vibration isolation system of Husqvarna petrol chainsaws. Made from durable, silver-coloured high‐tensile steel, it sits between the powerhead and the handle assembly to isolate engine vibration, helping maintain control and comfort over long cutting sessions. It is a direct-fit part for the Husqvarna 562 XP and 562 XPG platforms, matching the original geometry for correct preload and travel. Referenced by OEM No. 586 31 21 03 and MPN 586312103, it is a practical service item to restore the chainsaw's designed damping performance when an original spring is worn, stretched, or broken. Suitable for professional use and demanding DIY work where reliable handling matters.
Key Features:
- High‐tensile steel construction for strength and long service life
- Consistent vibration isolation helps reduce fatigue and improve cut accuracy
- Direct replacement with correct fitment for the AV system; no modifications required
- Stable performance in typical chainsaw environments (heat, oil, fuel mist, chips)
- Supports comfort and control during continuous felling, snedding, and bucking
- Matches OEM reference 586 31 21 03 and MPN 586312103 for easy identification
- Straightforward installation with basic hand tools
- Suitable for heavy-duty and professional applications as well as regular maintenance
Typical Applications:
Ideal when a chainsaw shows excessive handle vibration, poor isolation, or visible spring damage. Commonly replaced during routine servicing, after impacts, or following prolonged heavy use. Helps restore smooth handling and operator comfort in forestry, landscaping, arborist work, and firewood processing where steady control and reduced vibration are important.
