What is the primary function of a crankshaft hub?

The crankshaft hub is a key component at the front of the engine. It mounts to the crankshaft and serves as the attachment point for the crankshaft pulley, which drives accessories like the water pump and alternator via the serpentine or V-belt.

Why choose an aluminum crank hub over a steel one?

Aluminum hubs are lighter than their steel counterparts. This can contribute to a slight reduction in overall engine weight, which is often a goal in performance builds. Aluminum also offers good corrosion resistance.

Does this crank hub come with any installation hardware?

This product listing is for the crank hub only. It is recommended to refer to the manufacturer's installation instructions or consult with a professional to determine if any additional hardware is required for your specific application.
