This product was specifically developed for STIHL's professional high-end chainsaws MS201/MS201T/MS201TC. It conforms to the original factory specifications for chainsaw construction and includes a 40 mm cylinder-piston-cylinder liner assembly (drive unit). This component is the essential solution for restoring performance to MS201 series engines. It comprises key elements such as the cylinder block, piston, and piston rings. Manufactured strictly according to the manufacturer's technical standards, it guarantees dimensional accuracy, material properties, and thermodynamic characteristics that match the original parts. This eliminates power loss, starting difficulties, and insufficient compression caused by cylinder wear, piston ring failure, and cylinder seizure, fully restoring the engine's original performance and reliability.
