Description
Overview:
The Piston Ring 37mm for Stihl chainsaws is a Genuine Stihl part designed to restore and maintain correct engine compression. Manufactured from wear-resistant steel, it helps seal the combustion chamber, reduce blow-by, and support smooth starting and consistent power. This 37 mm diameter ring is made for compact Stihl two-stroke engines used in popular models such as the MS 170 and MS 193 C. Replacing a worn ring can improve throttle response, reduce fuel consumption, and limit exhaust smoke. Supplied to the original specification under Stihl part number 1130 034 3007, it is a direct-fit service item for routine overhaul or repair, helping extend engine life and protect the cylinder and piston from premature wear.
