DESCRIPTION
A piston kit is a crucial component of an engine, particularly in trucks. This kit, also known as a piston assembly or cylinder kit, consists of a piston, piston rings, and wrist pin. The part number 4089967 refers to a specific set of pistons that are designed to fit certain types of truck engines. The piston's main function is to transfer force from the expanding gases in the combustion chamber to the crankshaft via the connecting rod. Piston rings provide a seal between the piston and cylinder wall while also helping to regulate oil consumption and manage heat transfer. The wrist pin connects the piston and connecting rod together allowing for movement within the engine block. A high-quality piston kit is essential for truck engines as it ensures efficient combustion with minimal friction while reducing wear on engine components over time.
