DESCRIPTION
The engine piston kit, part number 4309403, is a set of components that includes the piston, rings, and wrist pin. The piston is a cylindrical piece that moves up and down in the cylinder bore, compressing fuel and air to create power. The rings provide a seal between the piston and cylinder wall to prevent combustion gases from escaping. The wrist pin connects the piston to the connecting rod which transfers power from the piston to the crankshaft. This kit is designed for use in truck engines and ensures proper fitment and performance when replacing worn or damaged pistons.
