Description
Overview:
This Genuine Husqvarna piston assembly is a direct replacement top-end component for selected petrol chainsaws, including the Husqvarna 555 and 560XP. The piston is manufactured from a durable aluminium alloy for strength with low weight, helping the engine rev freely and maintain good heat transfer. Supplied as a complete assembly with piston rings, gudgeon pin, and circlips, it restores correct compression and smooth running when the original piston is worn, scored, or damaged. Designed for 2‐stroke engines, it fits and operates exactly as the factory part. Identified by MPN 584 80 78‐06 (584807806), it offers reliable compatibility for professional forestry, arb work, and demanding domestic use where consistent power and easy starting are required.
