About this part

Product Details

If you're working on the crankshaft assembly for your 2014 or newer Corvette with an LT1 or LT4 dry sump engine, you'll want to pay close attention to the crank hub. This component is critical for ensuring the crankshaft's rotation is accurately transferred to other accessories and for maintaining proper timing. ATI's HT Steel Crank Hub is built for these specific applications, offering a well-built solution for enthusiasts who demand reliability.

This hub features a double keyway design, which is a notable improvement over the stock single keyway. The extra keyway provides a more secure connection to the crankshaft, reducing the risk of the hub spinning or slipping under high loads. Made from HT (High Tensile) steel, it's constructed to withstand the stresses associated with powerful LT engines. This makes it a solid option for Corvettes that see spirited driving or track use.

When you're rebuilding or modifying the front of your engine, ensuring every component is up to the task is key. This ATI crank hub is designed to fit right and offer a more robust connection than the factory part, giving you peace of mind.
