What is a Pop-Up Piston?
A pop-up piston, also known as a high-compression piston, features a raised or "pop-up" dome on the piston crown, which reduces the combustion chamber volume when the piston is at top dead center. This design increases the compression ratio, allowing for more efficient fuel combustion and greater power output from the engine. Specifically, the Cross Performance Pop-Up Piston Kit for Stihl 039 and MS390 chainsaws is engineered to enhance performance by delivering extra compression compared to standard OEM pistons.
