What is the main benefit of using an aluminum crank hub?

An aluminum crank hub is lighter than a steel one. This can help reduce rotating mass in the engine, which is often a goal for performance builds.

What does a crank hub do?

The crank hub attaches to the front of your engine's crankshaft and serves as the mounting point for the harmonic balancer. This ensures the harmonic balancer is properly secured and functions correctly.

What specific Ford and Chevy applications does this hub fit?

This hub is designed for Ford small block and inline 6-cylinder engines. It also fits Chevy engines with a front-mount distributor and Ford engines with a 3-bolt crankshaft configuration.
