About this part

Product Details

If you're working on a Chrysler 400 or 440 engine and need to replace the front crankshaft hub, this steel unit from ATI is a solid option. It's designed for engines with external balance, which is common for these big-block Mopar V8s. Getting the right hub is crucial for proper timing and accessory drive function.

This hub is made from steel, offering a strong and durable replacement for your original part. It's built to fit the front of the crankshaft and is specifically configured for externally balanced applications. This means it's the correct piece if your engine assembly relies on counterweights for balance rather than being internally balanced.
