What do harmonic balancers do?

Harmonic balancers, also known as crankshaft dampers or vibration dampers, are engine components designed to reduce engine vibration and dampen out potentially damaging torsional vibrations. They are typically made of two parts, an outer ring and a hub, separated by a layer of rubber or other dampening material. As the engine rotates, the harmonic balancer absorbs and dissipates any unwanted vibrations, helping to improve engine performance and reliability.

What is the difference between a harmonic balancer and a harmonic damper?

There is no difference between a harmonic balancer and a harmonic damper, as both terms are used interchangeably to describe the same engine component. Harmonic balancers are sometimes referred to as dampers because they are designed to dampen out unwanted engine vibrations.

How much does it cost to replace a harmonic balancer?

The cost of replacing a harmonic balancer can vary depending on the make and model of your vehicle, as well as the extent of the damage or wear to the existing harmonic balancer. On average, you can expect to pay between $600 and $900 for a new high performance harmonic balancer, not including the cost of labour for installation. It is important to address any issues with your harmonic balancer promptly to avoid potential engine damage or failure.
