About this part

Product Details

This kit includes the ATI crank hub and inner shell, both made from steel. It's designed for Chevy SB engines that feature a 3/16 inch second keyway positioned at 180 degrees.

The steel construction offers a solid foundation for your engine's front-end components. This specific setup is for those building or rebuilding a Chevy small block engine where precise timing and component alignment are critical. Having that extra keyway at 180 degrees can be important for certain accessory drives or timing configurations.
