Description

Overview:
This piston ring is a genuine Husqvarna spare for maintaining compression and restoring performance in Husqvarna chainsaw engines, including the 365 X-Torq and 372XP X-Torq. Made from high-quality materials for heat and wear resistance, it forms a tight seal between the piston and cylinder to minimise blow-by, support reliable starting, and maintain power under load. The ring is precision-made for a correct fit in the specified bore, with an outer diameter of 52.4 mm and a ring gap of 7.7 mm. It is a direct replacement for OEM No. 576 81 84-01, making it suitable for routine top-end maintenance or the replacement of worn or damaged rings. A good seal helps protect the cylinder, improve fuel efficiency, and extend engine life.

Key Features:
