ATI Shell Assy - 7.074 - Steel - 1987 Buick Grand National Ext Bal

This ATI Shell Assy is a steel crankshaft damper designed for the 1987 Buick Grand National with an external balance configuration. A crankshaft damper, often called a harmonic balancer, is crucial for absorbing torsional vibrations that occur in the engine's crankshaft. Without it, these vibrations can cause premature wear and even catastrophic failure of the crankshaft and other engine components over time.

This particular damper is constructed from steel, offering a well-built and durable solution for managing engine harmonics. Its 7.074-inch diameter is specific to the application, ensuring it works correctly with the engine's natural frequency. By effectively dampening these vibrations, this ATI damper helps protect your engine's internal components, leading to a more reliable and longer-lasting powerplant.
