ATI Crank Hub - Steel - Chevy SB w/1.60 Crank - 6 Bolt Chrysler - 2Pc Hub - 3/16 & 1/4 Keys - Blower

If you're building a high-performance Chevy small block engine, especially one intended for forced induction like a blower, you need a crank hub that can handle the extra stress. This ATI crank hub is made from steel, offering a solid foundation for your crankshaft's front snout. It's designed for Chevy SB engines with a 1.60-inch crank snout and features the 6-bolt Chrysler pattern, making it a versatile choice for many custom builds.

This hub comes as a two-piece design, which simplifies installation and allows for precise alignment. It includes both 3/16-inch and 1/4-inch keyways, so you can match the key to your specific application, whether you're running a blower or another type of accessory drive. The steel construction means it's well-built to resist the torsional forces common in performance engines, ensuring reliable operation under demanding conditions.
