DESCRIPTION
A Engine Piston Kit is a set of components that includes the piston, rings, and wrist pin. The piston is a cylindrical part that moves up and down in the engine cylinder bore to transfer energy from the fuel to the crankshaft. It is typically made of aluminum alloy and has grooves for mounting piston rings which provide a seal between the piston and cylinder wall. The wrist pin connects the piston to the connecting rod, allowing it to pivot as it moves up and down. A Engine Piston Kit, such as part number 4376349, is designed for specific engine applications and must be selected carefully based on factors such as bore size, stroke length, compression ratio, and intended use. Proper installation of a Engine Piston Kit is critical for engine performance and longevity.
