DESCRIPTION
A engine piston kit is a set of components that includes the piston, rings, and wrist pin that work together to transfer energy from the fuel to the engine. The piston is a cylindrical component that moves up and down in the cylinder bore. It is connected to a connecting rod via a wrist pin, which allows it to move freely while transmitting force. The rings are placed on the outer surface of the piston and provide a seal between the piston and cylinder wall while also regulating oil consumption. These components must be precisely manufactured and assembled to ensure proper engine function, making them critical parts for any truck engine. Part Number: 4089735 is a specific type of engine piston kit designed for use in certain truck models.
