ATI Crank Hub - Steel - LS1/2/3/6 Y Body G8 L76 - LSA & LT4 - 3-Bolt -.391 Thru Holes for A/C Pulley

If you're working on a GM LS-based engine, especially one with an air conditioning pulley, this ATI steel crank hub is a solid piece to consider. It's designed to replace the factory hub on LS1, LS2, LS3, LS6, L76, LSA, and LT4 engines, including those found in the Holden Commodore (G8) and other Y-body applications. This hub is crucial for securely mounting your harmonic balancer and ensuring proper timing and accessory drive function.

This particular hub is made from steel, offering a strong and durable replacement for your original. It features three 3/8-inch (0.391 inch) thru-holes, specifically set up to accommodate the mounting bolts for an A/C pulley. This means if your build requires air conditioning, this hub is ready to go without needing additional adapters for that specific component. It’s a well-made part that addresses a common need when upgrading or rebuilding these popular GM V8s.
