ATI Crank Hub - HT ST - LS1/2/3/6 Y Body / LSA/LT4 CTS-V / ZL1/LT1 Camaro - w/2 - 3/16 Keyways

If you're working on the crankshaft of your LS-based engine, especially a performance build like a Y-body, CTS-V, ZL1, or LT1 Camaro, you know how critical the crank hub is. This ATI Crank Hub is designed to be a strong replacement for your stock component, ensuring the timing and accessory drive systems stay properly synchronized. It's built to handle the demands of these powerful engines.

This particular hub comes with two 3/16-inch keyways. Having a second keyway offers an improved level of security for the hub's connection to the crankshaft, reducing the risk of the hub spinning on the crank under high stress. This is a well-built piece from ATI, a company known for its performance engine components, and it fits right into the specific applications listed, making it a solid option for your build.
