Dayco Engine Harmonic Balancer for 1970-1974 GMC P35 P3500 Van 7.4L V8 dd

• REDUCE VIBRATIONS: Harmonic balancers serve to absorb and reduce harmonic vibrations from the engine as the crankshaft rotates. Excessive harmonic vibrations at high engine speeds can cause accelerated wear and damage to other components. This heavy-duty, wear-resistant Engine Harmonic Balancer is an exact OE replacement designed to reduce wear, friction, vibration, and harshness
• EXTEND SERVICE LIFE: One of the first symptoms of a potential problem with the harmonic balancer is engine vibration. The harmonic balancer absorbs engine vibrations as engine speeds rise. As the harmonic balancer gets old, it can no longer properly absorb the harmonic vibrations, causing the engine to begin shaking excessively. Once the rubber layer in the harmonic balancer dries or wears out, it can cause the entire harmonic balancer to separate and fail completely
