Crankshaft dampers are crucial components designed to absorb torsional vibrations generated by the engine's crankshaft. These vibrations can cause stress and fatigue on the crankshaft, potentially leading to premature failure. Crankshaft dampers effectively reduce these vibrations, protecting the crankshaft and promoting engine longevity. Choosing a crankshaft damper should consider factors like material composition, weight, and compatibility with your specific vehicle and engine type.
