What is the purpose of a crank hub and inner shell assembly?

The crank hub and inner shell are key components of the crankshaft damper system. They help to absorb torsional vibrations from the crankshaft, preventing damage to the engine and ensuring smoother operation.

Why is the .005 undersize specification important?

The .005 undersize sizing is critical for engines that require specific, tighter clearances on the crankshaft snout. This ensures a precise fit for the damper assembly, which is vital for proper vibration dampening and engine balance.

What material is this crank hub and inner shell made from?

This ATI crank hub and inner shell assembly is constructed from steel, offering a strong and durable component for your engine's front end.
