Description
Overview:
This non-genuine Cylinder & Piston assembly is a direct-fit top-end replacement for Stihl chainsaws, engineered for the MS440 and 044. It features a 50 mm (1.97 inches) cylinder bore and a 12 mm (0.47 inches) gudgeon pin to match original sizing, helping restore lost compression and power.
