What is an external balance configuration?

An external balance configuration means that counterweights are added to the crankshaft, flexplate, or torque converter to achieve engine balance, rather than being integrated into the crankshaft or harmonic balancer itself. This ATI unit is designed to work with that setup.

What does a crank hub and damper do?

A crank hub and damper assembly is designed to absorb torsional vibrations from the crankshaft. This helps protect the crankshaft and other engine components from damage and reduces wear over time.

What material is this crank hub made from?

This ATI crank hub and inner shell assembly is constructed from steel, offering a solid and durable component for managing engine harmonics.

About this part

Product Details

This is the ATI Crank Hub & Inner Shell with Weight, designed for Chevy 454 engines with an external balance. It's a well-built component made from steel, intended to help manage torsional vibrations from the crankshaft.

The primary job of a crank hub and damper assembly is to absorb the shock and vibration that naturally occurs as the crankshaft rotates. This helps protect the crankshaft and other engine components from premature wear and potential damage. This particular unit is made from solid steel, offering a robust solution for managing engine harmonics. It's specifically designed for external balance configurations, meaning it's crucial to ensure your engine's balance factor matches this requirement for proper operation.

When installing this, make sure you're familiar with the specific requirements for external balance engines. Proper installation is key to ensuring it functions correctly and protects your engine.
