Worm Gear Compatible With Stihl Chainsaws MS290 MS310 MS311 OEM 1125 640 7110

This is a high-quality aftermarket replacement part, these parts are often made by the same company that make the branded parts, these Stens parts offer a really good alternative to OEM parts and are brilliant value, yes you may find cheaper but I doubt you will get the same quality of part unless you buy genuine replacement parts.
