Description
Overview:
This Genuine Stihl piston ring is a 44 mm x 1.2 mm (1.73 in x 0.05 in) replacement for 2‐stroke chainsaw engines, engineered to restore correct sealing between the piston and cylinder. Manufactured from high‐quality materials to cope with heat and high RPM, it helps maintain stable compression, clean running and reliable power delivery. It is designed for Stihl chainsaws using a 44 mm bore, including the MS 260 and MS 260 C, where accurate fit and correct ring tension are essential. By reducing blow‐by and oil contamination, a fresh ring supports easier starting, better throttle response and consistent cutting performance. Ideal for routine top‐end servicing or when wear is evident, it keeps your saw operating efficiently under professional or domestic workloads.
