Description
Overview:
This Genuine Husqvarna piston ring is designed for 38 cc (38 cm3) two-stroke chainsaw engines, maintaining a tight seal between the piston and cylinder to preserve compression, power, and efficient running. Made from durable, hardened steel with a precision-ground finish, it withstands heat and friction inside the combustion chamber. It is purpose-built for the Husqvarna 236 and also suits compatible 38 cc homeowner models such as the 120 Mark II. Fitting a new ring helps restore easy starting, steady idle, and clean acceleration when an engine has lost compression due to wear or damage. Ideal for regular servicing by tradespeople, arborists, and DIY users, it forms a key part of a top-end refresh to keep your chainsaw working reliably.
