Every diesel engine depends on a combination of parts working in harmony. Cylinder kits and pistons maintain compression, crankshafts transfer power, and valve inserts regulate airflow. Turbochargers increase efficiency, while gaskets and seals keep fluids contained under high pressure. Water pumps and cooling components prevent overheating during long hauls.
