By dampening torsional vibrations, it protects the crankshaft and other engine parts from premature wear. This pulley weighs approximately 2.61 kg and measures 194mm in length, 150mm in width, and 56mm in height. Opting for a genuine OEM damper pulley ensures the precise balance, material composition, and vibration dampening characteristics required for optimal engine performance and longevity, preventing potential damage from excessive harmonic resonance.
