Harmonic Balancers | Crank Pulleys & Vibration Dampers

The harmonic balancer mounts to the front snout of the crankshaft, absorbing and dissipating the torsional vibration generated by each combustion event before it can propagate through the rotating assembly and damage engine components. CBT Auto Parts stocks OEM-quality harmonic balancers and harmonic dampers for diesel and petrol engines, built to the correct specification for your application.

Part of our Engine & Powertrain Parts range alongside crankshafts and flywheels, our harmonic balancers cover platforms including 5.9 Cummins, 6.7 Cummins, 12V Cummins, LBZ, LS truck, and C5 Corvette. OEM-spec and performance harmonic damper options are stocked. Aftermarket crank pulleys meet OEM specifications, and orders ship worldwide with fast dispatch.

FAQs

1. What does a harmonic balancer do?

It absorbs and dissipates torsional vibration from combustion pulses at the front of the crankshaft, protecting the rotating assembly from fatigue damage.

2. How do I know if my harmonic balancer has failed?

Check for rubber layer cracking, oil contamination at the bond interface, and any rotational movement between the outer ring and inner hub. A displaced timing mark is the most common outward symptom of a slipped balancer.

3. Can I replace a harmonic balancer myself?

The balancer can be removed and refitted with the correct puller and installation tool; attempting to hammer it on or off damages the crankshaft snout and is not a correct procedure.

4. Is an aftermarket harmonic balancer reliable?

Yes, OEM-quality aftermarket units in the CBT Auto Parts range are manufactured to the same damping specification and material standards as the factory component.

5. Does CBT Auto Parts ship harmonic balancers internationally?

Yes, all orders are dispatched from our warehouse and shipped worldwide with fast fulfilment.
