ATI Crank Hub - Steel - Chevy SB - 6 Bolt Chrysler - Dual 3/16 Keys - Blower

This is the ATI Steel Crank Hub, designed for Chevy Small Block and 6-bolt Chrysler applications, specifically when using a blower. It's built to handle the demands of forced induction setups, ensuring a solid connection between your crankshaft and other essential components.

Constructed from durable steel, this hub is well-built to withstand the increased stresses associated with supercharged or turbocharged engines. It features dual keyways, each 3/16 inch wide, which provide a more secure engagement than a single key. This dual key setup helps prevent the hub from spinning on the crankshaft under high torque loads, a common issue in blower applications. The robust design aims to maintain reliable timing and power transfer.

If you're building a high-performance Chevy SB or Chrysler engine with a blower, this crank hub is a solid option for ensuring your crankshaft is securely coupled to your accessories and timing components.
