Description
Overview:
This Genuine Stihl piston ring is designed to restore and maintain compression in 2‐stroke chainsaw engines. Sized 44.7 mm x 1.2 mm (1.76 inches x 0.05 inches), it provides a precise seal between the piston and cylinder to support reliable starting, steady idle, and full cutting power. Made from durable, wear‐resistant metal for long service life, it is engineered for the Stihl MS260 and MS260C platforms, matching the correct bore and ring groove specification. As an OEM component (often supplied under code 1121 034 3002), it fits correctly without modification and integrates with the standard piston and cylinder set‐up. Ideal for routine top‐end refreshes or repairs after scoring or loss of compression, it helps keep professional and domestic saws working efficiently.
