Piston Ring Kit for Husqvarna Chainsaws

This kit supplies two replacement piston rings sized at 46 mm diameter and 15 mm width. It is manufactured by LAHDEK as a new spare part for petrol-powered chainsaws. The rings are designed to restore compression in two-stroke engines used across several Husqvarna models.

Suits owners of listed Husqvarna saws.

The rings fit Husqvarna models 51, 55, Rancher, 257, 357, XP EPA and 359 EPA when the original piston measures 46 mm. They replace OEM part number 503289014. Buyers with different piston diameters or non-Husqvarna saws should look at other parts.

Maintains seal under continuous cutting load

During extended cutting sessions the rings keep their tension and resist blow-by, preserving engine compression. The 46 mm by 15 mm dimensions match the cylinder groove so the seal stays consistent as the engine heats up. This steadies power delivery over long work periods.
