What is the main purpose of a crank hub?

The crank hub is a component that attaches to the front of the crankshaft. Its primary role is to provide a secure mounting point for the harmonic balancer, which helps to dampen torsional vibrations in the engine.

Why would someone upgrade from a stock crank hub?

Owners often upgrade the crank hub when building a performance engine or when the stock component shows signs of wear or potential failure. A stronger aftermarket hub can better withstand the stresses of higher horsepower applications and ensure the harmonic balancer remains properly seated.

Does this crank hub come with any hardware?

This product listing is for the ATI Steel Crank Hub (Part# ATI916031) only. It is designed to utilize the factory hardware for installation, but it's always recommended to inspect your existing hardware or consult the manufacturer's installation guide.
