DESCRIPTION
The Engine Piston Kit (part number 4089844) is a set of components that includes the piston, piston rings, and wrist pins. The piston is a cylindrical component that moves up and down inside the engine cylinder to convert the energy from fuel combustion into mechanical motion. The piston rings are installed around the circumference of the piston to seal it against the cylinder wall and prevent oil from leaking into the combustion chamber. The wrist pins connect the piston to the connecting rod, which in turn connects to the crankshaft to transfer power to other parts of the vehicle. The Engine Piston Kit is an essential part of any internal combustion engine as it directly impacts its performance and efficiency.
