This multi-model cylinder assembly is a core power part for MS series chainsaws (MS170/MS180/MS250 etc.), FS55 trimmer and SR420. It features a finned cylinder block (enhances heat dissipation during high-load operation) and a precision-machined metal piston.

Designed to match each model's engine dimensions, the assembly installs without modification. The piston rings ensure airtightness between piston and cylinder, while the durable materials reduce wear—supporting stable operation for logging (chainsaws), grass-cutting (trimmer) and SR420's tasks.
