DESCRIPTION
A engine piston kit is a set of components that includes pistons, piston rings, and pins. The kit is designed to replace the existing pistons in an engine. Pistons are cylindrical components that move up and down within the engine's cylinders, converting the energy generated by combustion into mechanical energy that powers the vehicle. The piston rings help to seal the gap between the piston and cylinder wall, preventing oil from leaking into the combustion chamber while also helping to regulate oil consumption. Piston pins connect the piston to a connecting rod, which then transfers power to the crankshaft. The 4309401 engine piston kit is specifically designed for use in a truck engine and can be used as part of routine maintenance or during an engine rebuild.
