This small Chevrolet part known as Chevrolet Tahoe Harmonic Balancer maintains the equilibrium of the engine and controls the twist and turn by decreasing torsional distortion and vibration on the crankshaft. It basically has a metal core, a wide bulky metal inertia ring, and rubber band through which the inertia ring opposes twisting forces from the crankshaft. However, to the engine they present possible dangers after they have been exposed to heat, road salt, and fluids like oil that weaken rubber's strength. Performance harmonic balancers may come in different types including the traditional construction, viscous fluid, and the multi-piece balancers that are tunable and rebuildable, to give the premier protection at all RPMs though it may be said that standard OE balancers may not be sufficient for highly modified engines.
