ATI Crank Hub - HT Steel - LS1/2/3/6 Y Body - G8 L76 - LSA & LT4 CTS-V & ZL1 - LT1 - Double Keyway

If you're working on a high-performance LS or LT engine, especially one that sees track time or aggressive street use, you know the importance of a solid crank hub. This ATI HT Steel Crank Hub is built to handle the extra stress these engines can put on the crankshaft snout. It's designed to work with a variety of popular GM LS and LT platforms, including the LS1, LS2, LS3, LS6, G8 with L76, LSA and LT4 engines found in the CTS-V and ZL1, and the LT1. This hub features a double keyway design, which adds an extra layer of security against torsional flex and slippage, a common issue when increasing horsepower or using aggressive camshafts.

Crafted from heat-treated steel, this hub offers a strong and durable foundation for your harmonic balancer. The double keyway setup means you'll have two keys working together to lock the balancer to the crankshaft, providing a more robust connection than a single keyway setup. This improved connection is crucial for maintaining proper timing and preventing damage to the crankshaft snout under high load conditions. It's a well-built component that addresses a known weak point in many performance LS and LT applications.
